How to increase Speed in Ubuntu

If you are suffering from Slow internet while surfing net in Ubuntu than now you just dont need to worry about it because i’ve found one simple solution to this problem. I’ll provide two different solutions if one doesnot work then the other will definitely work.
1. First Step
root@desktop:~$ vi /etc/resolv.conf
#Generated by NetworkManager
nameserver 208.67.222.222
nameserver 208.67.220.220

#press Esc and wq! and then enter
root@desktop:~$
2. Second Step
root@desktop:~$sudo gedit /etc/modprobe.d/aliases

Find the line “alias net-pf-10 ipv6″ and comment it.
#alias net-pf-10 ipv6
After you comment it copy that line and replace ipv6 with off
alias net-pf-10 off

Increase the Speed in Which Firefox loads pages

1. Type “about:config” into the address bar and hit Enter.
(Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.)
2. Alter the entries as follows:
Set “network.http.pipelining” to “true
Set “network.http.proxy.pipelining” to “true
Set “network.http.pipelining.maxrequests” to some number like 10.
This means it will make 10 requests at once.
3. Lastly, right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0“;.(Zero)
This value is the amount of time the browser waits before it acts on information it receives. If you’re using a broadband connection you’ll load pages faster now.
Optionally (for even faster web browsing) here are some more options for your about:config (you might have to create some of these entries by Right Click –> New– > Interger or String
network.dns.disableIPv6: set “false” 
content.notify.backoffcount”: set “5“; (Five)
plugin.expose_full_path”: set “true”.
ui.submenuDelay”: set “0; (zero)

Reduce RAM usage to 10mb when Firefox is minimized:

This little hack will drop Firefox’s RAM usage down to 10 Mb when minimized:
1. Open Firefox and go to the Address Bar. Type in about:config and then press Enter.
2. Right Click in the page and select New -> Boolean.
3. In the box that pops up enter “config.trim_on_minimize”. Press Enter.
4. Now select True and then press Enter.
5. Restart Firefox.
These simple tweaks will make your web browsing with Mozilla Firefox 2-3 times faster and easier.
