Before starting
Update information repositories and all the packages we have installed so far.
sudo apt-get update && sudo apt-get upgrade
1. Tuning Swappiness
sudo nano /etc/sysctl.conf
vm.swappiness=10
2. Concurrent booting
sudo nano /etc/init.d/rc
CONCURRENCY=makefile
3. Prelinking
sudo apt-get install prelink
sudo nano /etc/default/prelink
PRELINKING=yes
sudo prelink -ua
4. Install 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
sudo /etc/init.d/preload restart
5. Blacklist ipv6
If you are using ipv6 please skip this tip. Else if you disable IPv6 you can get reasonable Internet connection and DNS speeds. Edit the file /etc/modprobe.d/blacklist.conf:
sudo nano /etc/modprobe.d/blacklist.conf
# disable ipv6 blacklist ipv6
6. TCP tuning
Like most modern OSes, Linux now does a good job of auto-tuning the TCP buffers, but the default maximum Linux TCP buffer sizes are too small. You can edit the /etc/sysctl.conf:
sudo nano /etc/sysctl.conf
Then add the following:
#ipv4 net.ipv4.tcp_fin_timeout = 60 net.ipv4.tcp_retries1 = 3 net.ipv4.tcp_keepalive_probes = 9 net.ipv4.tcp_keepalive_time = 7200 net.ipv4.tcp_syn_retries = 5 net.ipv4.tcp_timestamps = 1 net.ipv4.tcp_window_scaling = 1 net.ipv4.tcp_sack = 1 net.ipv4.tcp_no_metrics_save = 1
Now reload the changes:
sudo sysctl -p
7. Ubuntu tweak
Ubuntu Tweak is a must have application for Ubuntu, it is an application to configure Ubuntu easier for everyone.
Install Ubuntu Tweak in Ubuntu via repository, open terminal and enter the following command:
sudo add-apt-repository ppa:tualatrix/ppa
Then:
sudo apt-get update && sudo apt-get install ubuntu-tweak
