Speeding up MySQL reads using noatime

Link to this post 15 May 09

Here's a little secret not many Linux administrators know:
If you don't care about post-mortem analysis of a system and just want it to perform much faster, especially if you're running MySQL just remount the partition where your databases are stored with the noatime option:

[root@host]# mount -o remount,noatime /var/lib/mysql

This will improve the system I/O by at least 25%.
The only drawback is that none of the file's atime (access time) will be updated.

No journaling right? Wouldnt file system type selection also be important?

This works on any journaling file system like ext3
