Test your browser's Max Connections

Test your browser's max connections at...
http://stevesouders.com/hpws/max-connections.php

K-meleon loaded the full complement of pictures on my computer. Firefox loaded much fewer.

This doesn't necessarily mean that one browser is better than another BECAUSE of max connections. It's just something to know & ponder (if it is your wont to ponder.)

Interesant test:

K-Meleon 1.5.4 => Page load time: 13840 ms. All images showed.
Firefox 2.0.0.22pre => Page load time: 14361 ms. 5 images not showed.

Both with the same config in prefs:
network.http.max-connections => 24
network.http.max-connections-per-server => 8

Thanks neophyte! The info on that page finally helped me understand something about K-Meleon's settings that have been bothering me. The default setting for the network.http.max-connections-per-server preference is 8, as desga2 posted. I now realize that prior to using K-Meleon I suppose was used to IE's (and perhaps even FF 1.5's) 2 connections per server.

I'm on a slow dialup connection that is often slowed further after it rains. On pages with multiple large images (like screenshots) I'd noticed that K-Meleon was loading too many at once (eight, I suppose). With the pixels of that many images coming in so slowly it's been torture (beyond the everyday torture of dialup), particularly in this era of ignorant broadband users who throw uncompressed PNGs around like confetti.

I have now (experimentally) adjusted the max-connections-per-server to 2, to take me back to a setting that worked well with a slow connection. Two images loading at a time in a single tab feels much faster, offering my eyes some visible and timely progress. Other dialup users might do well to tweak this setting.

Footnote: It's later now and I'm not sure if this setting works well or not because it often locks down the loading of multiple tabs from the same site in way that I don't recall seeing in previous browsers, so there may have been some other balancing behaviours in play.

Egocentric people who crank up the number of connections to a server beyond reasonable limits are in effect launching a small denial of service attack against a server, creating excessive server load and tying up connections that others could use, particularly on small servers. This point is well understood in the realm of download managers, where anything more than two connections for large files is just plain greedy. Many servers limit the number of connections for these reasons, often to two.

Good schtuff, Doon. Even though I am on broadband , I learned something new!

you may want to bump the numbers up to the following:

network.http.max-connections => 64
network.http.max-connections-per-server => 16

WHY!
cuz Opera version 10.50 & higher have "max connections per server" with a default value of "16" and "max total connections" with a default value of "64".
If you don't believe me, install Opera 10.50 or greater on your machines, then from the Opera menu bar, click on Tools, Preferences, click on the Network section and click on the Advanced tab and look at the "default" values for max connections.

and FF 3.5/3.6, SM 2.0.x default values for "max connections" are the following:
network.http.max-connections => 30
network.http.max-connections-per-server => 15

I checked those myself.

I'm tweaking the values to get the best performance and speed, with all the images loaded, currently my choose is:
network.http.max-connections-per-server 2
network.http.max-connections 25
network.http.keep-alive.timeout 175
Supposedly my connection is fast 5MB, but of course that is not the true speed, because the wires (shared connection with the telephone) are from the seventies. grinning smiley The internet/phone provider will not invest on wires, desga2 probably know the company because it is from Spain.

slayer, I found out in mozilla/gecko based browsers like Firefox, Seamonkey and K-meleon that those following values ARE RENDERED WORHTLESS, unless you change the following in the about:config dialog box:

network.http.max-persistent-connections-per-proxy
network.http.max-persistent-connections-per-server

by default "network.http.max-persistent-connections-per-proxy" is set to 8 and "network.http.max-persistent-connections-per-server" is set to 6.

try setting both "persistent connection" values to "10" and see what happens. now those two mentioned above will have REAL, ACTUAL effects on performance in loading web pages.

another site to test max connections:
http://www.spasche.net/files/parallel_connections/

also, you folks may want to read this:

the tips there may also apply to K-meleon & Seamonkey users

IE6 took 58153 ms to load with 167 images. Reload was the same.

Opera 10 took 48544 ms to load with all images. Reload took 49904 ms and loaded all images.

KM 1.5.4 took 921 ms to load with no images. Reaload took 578 ms to load, still with no images. KM 1.5.4 is not set to not block anything, not even js or images. I don't have any problems loading images at other web sites except where they are blocked by AB+. With AP+ is disabled for http://stevesouders.com the load time was 375 ms but still with no images. Does anyone have any idea why KM 1.5.4 cannot load the images?

I am using Windows XP SP3 on a 2.67 MHz PC.

@caktus,
Could it be related to have too many connections (network.http.max-connections) at the same time? I can't see some images if I set that value too high.

I removed all custom connections settings returning them all to default but no change. It seems particularly strange that the problem does not seem to effect any other sites that I visit.confused smiley

The test site works retrieving the images from many servers, and if the browser tries to get all the images at the same time, it could not load some.
You could try to set the network.http.max-connections-per-server to a lower value to see what happens, and there is no need to close KM, the changes will work right away, well that is what I think but I'm not an expert.

What about network.http.pipelining is anybody using that? Does it work?

it might. I set network.http.pipelining to "true" and network.http.proxy.pipelining to "true" AND network.http.pipelining.maxrequests to either "8" or "10"

slayer and caktus: I hope you're NOT ignoring network.http.max-persistent-connections-per-proxy and network.http.max-persistent-connections-per-server. otherwise, I will get on your case until you modify those and post here that you did adjust those "persistent" max connection settings. those two "persistent" max conn settings are VERY important.

set network.http.max-persistent-connections-per-server the same value as network.http.max-connections-per-server and see what happens in K-meleon.

Yep. Did all of the above but still no images at [stevesouders.com] will load.

Try the Spasche.net "parallel connections" site:
http://www.spasche.net/files/parallel_connections/

If you get "0" simultaneous connections on that one, then I think you need to use a new K-meleon user profile since it may be corrupted. since you're using XP, did you install "Multi-user Profiles" during KM 1.5.4 setup? If so, locate the "\Documents and Settings\username\Local Settings\Application Data\K-Meleon" and "\Documents and Settings\username\Application Data\K-Meleon" folders and delete them [where username is your XP username]. Then from the \Program Files\K-meleon\components\ folder, delete the "compreg.dat" and "xpti.dat" files and then re-load K-meleon and try either the [stevesouders.com] or [spasche.net] site.

most of your user settings will be lost when creating a new user profile for K-meleon though.

btw caktus, are you using a broadband internet connection [cable, DSL or LAN] or a dialup internet connection [56k or ISDN]?

Try the Spasche.net "parallel connections" site:
http://www.spasche.net/files/parallel_connections/
It indicates "Your browser seems to use 8 simultaneous connections to this server." And 8 isin fact the value.

I thought that I had deleted the "compreg.dat" and "xpti.dat" files but I guess I was mistaken. I deleted them and restarted the browser including the Loader.exe and these files were recreated. I tried [stevesouders.com] again but no change.

Could it be that the profile is in fact corrupt? As with prevoius versions of KM I created a blank profile.ini in KM's main directory. There is also a Profile.ini with these values: [Profile0]
Name=default
Path=vap3bh21.default
IsRelative=1
Default=1
[General]
StartWithLastProfile=1

in the Profiles folder.

I am using dialup with a 56k modem.

8 connections is probably the max you can get. Try reducing the network.http.max-connections value and reload the page. If something goes wrong, just right click over a preference an reset it.

no wonder, caktus. you need to upgrade to faster broadband connection soon. dialup connections may be insufficient for the [stevesouders.com] site to work properly in KM.

you may want to set the following:
network.http.max-connections to either "24" or "32"
network.http.max-connections-per-server > "8"
network.http.max-persistent-connections-per-proxy > "8"
network.http.max-persistent-connections-per-server > "4"

if problems continue at the stevesouders.com site with K-meleon, then you need to get broadband internet service. try testing the site on a friend's or relative's computer that has broadband connections to be sure.

and silly slayer has not even mentioned about network.http.max-persistent-connections-per-server. does he know that it exists? why has he not talked about it or say that he modified its value?

Yes 4td8s, I have changed that value too, I have everything at 6 at the moment and I'm testing which value is the best for me.
network.http.max-connections-per-server 6
network.http.max-persistent-connections-per-server 6

I have network.http.max-connections at 35, which is faster on most sites, but I can not get all the images loaded from the test site.
Pipelining does nothing with my connection.
What about network.http.request.max-start-delay? I have been playing with it too.

@ 4td8s & slayer

Tried all, still no progress. I have KM on the machine of a friend who has RR; I'll give it a try just to see if it makes a difference. However, it apparently doesn’t really matter in my case since I rarely have any trouble with any other sites images of consequence. Usually the only trouble with images I have is the ones I don't like, and AB+ makes it a piece of cake to get rid of them. AB+ is clearly one of the best freeware app's available. I plan on staying with my discount dialup ISP. But if anyone has any other methods I would like to try them.

My network.http.max-connections was set at "60" for some reason, I don't think that is default. I currenlt have it set at "32" and so far I see no difference.

There should be a blank file called profile.ini in your main K-meleon Folder.

There also should be a profiles.ini file in your c:\program files\k-meleon\profiles sub-folder.

Caktus,

I have an old Pentium M 1248 Mhz, with only 768 Megs RAM... a ThinkPad T40 running XP PRO SP3.

I have no problem loading that site with the default settings in KM 1.5.4. It has to be your settings or perhaps the dialup??? But no images at all? Strange.

Sorry I was so slow to respond, Guy's. Been out of town for several days.

I am now noticing the same problem on some other sights. One site is us.toluna.com, a consumer survey site that sometimes opens what I believe are frames which show survey questions with options to select responses with radio buttons or check marks. Sometimes, within these frames are also images. Sometimes either the response options do not appear and somestimes the images do not appear, and somtimes neither appear, but only sometimes.confused smiley

If you want to see the types of frames to which I am refering go to us.toluna.com and under "Sponsored Polls" on the right-hand side of the page click on one of the text links text links i.e. "I would like to talk to you about your consumption alcoholic beverages, drunk both on their own and...
Answer now and earn 60 points!."

@caktus

Sorry to bump an old thread, but I recommend you (and anyone else who's on dialup) try Opera. It has a special feature called 'Opera Turbo'. It will compress pages and images, making them load faster. It still won't make it as fast as a broadband connection, but it's still faster than without using it.
