For performance issues we have monitored our webserver with the tool "iostat" and recognized many write-requests on the htdocs- partition.Can anyone explain to me where this write-requests do come from? Who is writing and what/why?In a test we requested only static html-pages which can't write temporary files. Nevertheless we had this write-requests.Just a guess but perhaps updating the atime or something like that (last-accessed) time of the file? I know I saw awhile ago a document saying to increase performance to mount noatime on filesystems for web/file serving...
We had the same issue a year-or-so ago on one of our Gentoo/Linux boxes running ReiserFS. Mounting the partition with the "noatime" option fixed it in our case.
