Speed up UBUNTU

9 07 2008
1. Disable IPv6
Edit /etc/modprobe.d/aliases and change the line:

alias net-pf-10 ipv6

to

alias net-pf-10 off #ipv6

2. Run boot processes in parallel
Edit /etc/init.d/rc and change:

CONCURRENCY=none

to

CONCURRENCY=shell

3. Aliasing hostname to localhost
Modify /etc/hosts‘s first two line as follows:

127.0.0.1 localhost yourhost
127.0.1.1 yourhost

where yourhost, is your chosen hostname. This will fasten up applications load.

4. Preload
Preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.

sudo apt-get install preload

5. Swappiness
Let’s use swap less frequent. It will faster switching between applications.

sudo sysctl vm.swappiness=10

And edit /etc/sysctl.conf and add the line at the end of the file to set it automatically at boot time:

vm.swappiness=10

7. Profile grub
Grub cap profile your startup, it’s a kind of index on file read at boottime, so after the first time (when it builds the index) it will access those files faster.
Edit /boot/grub/menu.lst and place “profile” at every line’s end witch is starting with “kernel /vlminuz…”

UPDATE: remove if after the next boot.

8. Speed up your HDD
Install hdparm with

sudo apt-get install hdparm

and enable 32 bit IO and UDMA if it wasn’t before with:

hdparm -c3 -d1 /dev/yourdevice

where /dev/yourdevice is your HDD.
And to make it persistent you also need to edit /etc/hdparm.conf, and make it run at every startup, so you have to enable the “Hard disk tuning (hdparm)” service with System->Administration->Services.

9. Speedup Broadband Internet

You have to open your /etc/sysctl.conf file back up again.

scroll to the bottom and just add these lines to it.


net.core.rmem_default = 524288


net.core.rmem_max = 524288


net.core.wmem_default = 524288


net.core.wmem_max = 524288


net.ipv4.tcp_wmem = 4096 87380 524288


net.ipv4.tcp_rmem = 4096 87380 524288


net.ipv4.tcp_mem = 524288 524288 524288


net.ipv4.tcp_rfc1337 = 1


net.ipv4.ip_no_pmtu_disc = 0net.ipv4.tcp_sack = 1


net.ipv4.tcp_fack = 1net.ipv4.tcp_window_scaling = 1


net.ipv4.tcp_timestamps = 1net.ipv4.tcp_ecn = 0


net.ipv4.route.flush = 1

or the sysctl to take effect.

sudo sysctl -p





EVANESCENCE "Field Of Innocence"

9 07 2008


I still remember the world
From the eyes of a child
Slowly those feelings
Were clouded by what I know now

Where has my heart gone?
An uneven trade for the real world
Oh I, I want to go back to
Believing in everything and knowing nothing at all

I still remember the sun
Always warm on my back
Somehow,it seems colder now

Where has my heart gone?
Trapped in the eyes of a stranger
Oh I, I want to go back to
Believing in everything

[Latin hymn:]
Iesu, Rex admirabilis
et triumphator nobilis,
dulcedo ineffabilis,
totus desiderabilis.

[Translation:]
O Jesus, King most wonderful
the conqueror renowned
the sweetness most ineffable,
entirely desirable.

[Man:]
“As the years pass by
Before my face,
As wars rage before me,
Finding myself
In these last days of existence,
This parasite inside me,
I forced it out.
In the darkness of the storm
Lies an evil,
But it’s me.”

Where has my heart gone?
An uneven trade for the real world
Oh I, I want to go back to
Believing in everything

Oh where, where has my heart gone
Trapped in the eyes of a stranger
Oh I, I want to go back to
Believing in everything

I still remember.
