#37944 [Bgs]: Very Slow session_start on nfs-mount

ID: 37944 User updated by: g42 at gmx dot net Reported By: g42 at gmx dot net Status: Bogus Bug Type: Session related Operating System: Gentoo Linux 2006.0 PHP Version: 5.1.4 New Comment: sorry, but a difference of 60 seconds just can't really be a problem of slow I/O. It's some kind of timeout i think, because all other sites on this share are fast as hell, except those who use sessions as well... if i change session.save_path to "/tmp" (which is on a local reiserfs-partition) everything runs smooth and without these problems... Previous Comments: ------------------------------------------------------------------------ [2006-06-28 10:29:55] tony2001@php.net Apparently it was bad idea to use NFS for script, as I/O operations are very slow with NFS. Not PHP problem. ------------------------------------------------------------------------ [2006-06-28 10:04:23] g42 at gmx dot net Description: ------------ Some PHP-Sites take very long to load (>60 seconds). A famous example is phpmyadmin. The wait-time accours after login, oder after changing the database. CacheGrind (created with xdebug) shows that php::session_start takes 60.011ms to start (1 call) while changing to another Database. The total script took 60.112ms php.ini changes: session.save_path = "/www/phptemp/sessions" /www is a nfs-mount, mounted with options: soft,retry=5,nfsvers=3,posix,tcp server-export: /raid/www 192.168.1.0/24(rw,sync,root_squash) Reproduce code: --------------- see phpmyadmin-2.8.1 http://www.phpmyadmin.net Expected result: ---------------- script-execution time <1 second Actual result: -------------- script-execution time >60 seconds ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37944&edit=1
