New Ubuntu Feisty Fawn 7.04 is almost here. Its better, nicer, quicker but it can never be quick enough. So if you want to perform few simple tweaks to speed up your Ubuntu Feisty read on.
Here is a collection of settings to tune up the speed and
performance of Ubuntu Feisty 7.04 and some of its applications.
Use them at your own risk and post a comment about your experience.
If you want to use it on Kubuntu change gedit to kate and gksudo to kdesu.
1. Disable IPv6
Most people don't need IPv6 yet so this is what I do to disable it. More here...
gksudo gedit /etc/modprobe.d/aliases
And change the line:
alias net-pf-10 ipv6
to:
alias net-pf-10 off #ipv6
This will disable IPv6 on all network interfaces. You need to reboot.
2. Run boot processes in parallel
This will make upstart to run the boot processes in parallel and speed up the boot process.
gksudo gedit /etc/init.d/rc
Find and change the line:
CONCURRENCY=none
to:
CONCURRENCY=shell
3. Aliasing hostname to localhost
Right
or wrong, you decide. But I picked this up in the Ubuntu forums the
other day and it does improve the startup of some apps.
gksudo gedit /etc/hosts
and add you hostname to the first line after localhost like this:
127.0.0.1 localhost yourhost
127.0.1.1 yourhost
4. Disable pango
I
know that this is already taken care of in Firefox but it still makes a
good performance boost to Thunderbird and some other apps.
gksudo gedit /etc/environment
and add:
MOZ_DISABLE_PANGO="1"
5. Preload
It does what you think. It preloads most common used libs and files = faster startup times on your applications.
sudo aptitude update
sudo aptitude install preload
What about prelink?
Prelink
is no longer necessary in feisty. Feisty uses a new linking mechanism
called DT_GNU_HASH which speeds up the linking process without the need
for continuously running prelink.
6. Swappiness
The
default value for vm.swappiness is 60 in Ubuntu Feisty which is a good
default value but if you want to tweak the performance a little bit
more you can change this value to a lower value to reduce the load of
the swap. If you run the follwing command:
sysctl -q vm.swappiness
You will see that the value is set to 60. And by running:
sudo sysctl vm.swappiness=10
You
will change the value from 60 to 10 which will make your system write
to swap a lot less and I would recommend this to everyone that has 512MB of memory or more. If you find that you have very little use of swap
set the value to 0. This will not disable the swap but it will make
your system write to the swap as little as possible and keep as much as
possible in memory. This makes a huge improvement when switching between
applications since they are now likely to be in physical ram instead of
on the swap partition.
To set your value permanent you need to change the sysctl.conf file:
gksudo gedit /etc/sysctl.conf
Add the line
vm.swappiness=10
To the end of the file. This way it will be set upon boot.
I've found that the value of 20 works very well on my laptop and I have 512Mb of memory. More info here >>
7. Profile grub
There
is a option to grub called profile which will profile your startup.
What it does is that it kind of indexing all the files read during
boot/startup and later on it will find and read those files quicker.
Hit the escape button when booting to get to the grub menu.
Select your default boot kernel and hit the e button.
Go down to the second line and hit the e button again.
Add profile to the end of the line and press enter.
Hit the b button to boot with your new option.
The
first time it will take a little bit longer to boot because it has to
build the index (or whatever they want to call it) but every boot after
this will be a lot smoother.
You need to do this every time you
update your kernel or have made other huge changes to your system that
might affect the files needed during boot.
8. Applications
Just few things that might help.
Firefox
Use Swiftfox instead. It's optimized for your CPU.
Install the fasterfox add-on
If it's not already set, disable IPv6. In the url enter about:config and find the ipv6 entry and disable it.
Install adblock plus add-on
to disable ad's.
OpenOffice
If you don't need that extras that java JRE provides then simply disable it openoffice. That's what I do.
