Have you edited or tweaked your pipeline settings in Firefox?http://rpk-tramplin.ru

You can do it by typing about:config in your firefox url tab.

Most blogs and tutorial will tell you to set high values to improve the speed, such as this one: www.mydigitallife.info/2007/10/16/speed-up-your-firefox-by-adjusting-your-http-pipelining/

Many people will go crazy and make values even higher such as:

network.http.pipelining.maxrequests 32
network.http.max-persistent-connections-per-proxy 128
network.http.max-persistent-connections-per-server 128
network.http.max-connections-per-server 256

These settings are very high and will create at least 32 connections to your server.

if you have many images and SSI includes, it could overload your apache webserver.
If you use apache2.2 with worker_mpm it will create 1 thread for each connection, thus you will have 32 new threads forked within just a few seconds.

Of course if you have a quad-core server with lots of ram you should not bother to read this.
But for most cheap vps and single core servers, it can really help.

so how you do it? simple, just use iptables conn_limit module

you may need to adjust the order or to insert or append like

# to apped to the end of the INPUT chain:
iptables -A input …
or
# to insert at position 10 of the input chain:
iptables -I input 10 …

I have tested this schema and work very well with firefox pipeline freaks.

the server will only then take up to 8 simultaneously connections per IP

to test the established connections you can try with netstat from the server:

Any comments, suggestions are welcome …

Update:

This can be not so good to legit users behind a proxy or firewall, because the the IP will be unique to all users behind the proxy/firewall.

in this case, you would increase the limit value.

Firefox does a lot of IO to the disk even thou you have lots of spare Ram, due to Sqlite, Bookmarks, History and Cache.senior project research paper cover page

To make Firefox faster is to store the whole profile folder into a Ram Disk.
RamDisk in Linux are called TmpFS. You can also use shared memory folder /dev/shm if you have it in your fstab.

This http://jaorswwa.org/energy-casino-bonus-codes-eingeben/ in the gentoo forums explains how to do it in Gentoo linux.

I made a similar script to make it work in OSX Leopard.

The Script have 2 parts, Start.sh and Stop.sh
Here are the Scripts:

Start.sh

Stop.sh

You can also use ‘tar’ instead of ‘rsync’. I just love rsync more.

* Warning: The ramdisk contents will be erased after you umount the ramdisk.

Have fun.

Gentoo Linux ROCKS
