I do this all of the time, it's not a huge speed gain, but it does remove the overhead of a filesystem write for every fopen(). I've not run into any problems with this and have used it with various software ( PostgreSQL, MySQL, Sendmail, mod_perl, vanilla Apache, etc, etc. ) on both ext2 and ext3. I doubt it will cause you a problem. Think about this way, when was the last time "last accessed time" was useful to software you were writing? :) It's almost always last modified that you need/want. --------------------------------- Frank Wiles <[EMAIL PROTECTED]> http://www.wiles.org ---------------------------------
