It absolutely helps performance. Atime is access time. Otherwise basically
everytime a file is accessed, the atime is updated. This causes a lot of
little writes to the hard drive constantly.
I have recently begun turning it off on our servers in the past 2 years
because in 10 years, I've never looked at the record for any purpose
whatsoever. I'm sure if you need to know the last time the file was
accessed, this would be bad to turn off though. However, for all practical
purposes, the mtime (modified time) is what people want.

Most of the apache tuning guides, as well as the MySQL docs, recommend
turning off atime on your filesystem (setting noatime). Are other people
doing this? Do you know if it has helped with performance? Have you
found any problems with it?
