Best-Performance-with-Linux-SSD.jpg[FONT=&amp]

When you want to buy a VPS, most of them use SSD, because a SSD have a better capacity for reading/writing than a Hard Drive and it also have a response time up to 40x faster than HDD.

[/FONT]
[FONT=&amp]But there are some small configuration to edit to get the best performances with your SSD as linux systems are not totally optimized for them.
[/FONT]
[FONT=&amp]So we will see how to speed up your VPS and how to configure debian/ubuntu to use a SSD properly. For a new install of a server the rules are :

[/FONT]

  • Use a recent linux system : Kernel 3.60+
  • Keep some free space on a disk (5-15%)
  • Use ext4
  • in /etc/fstab add the noatime setting


Code:
# / was on /dev/sda1 during installation
UUID=33XXX-XXXX / ext4 noatime,errors=remount-ro 0 1
  • Limit the swap usage :
Code:
cat /proc/sys/vm/swappiness
[FONT=&amp]The system should answer 60. So you just have to add the line below in /etc/sysctl.conf
[/FONT]
Code:
vm.swappiness=1
[FONT=&amp]Then reboot your system. And it's done your VPS should already be faster[/FONT]
