No, seriously you need to provide a LOT more information about your = configuration for anyone to get the foggiest idea about what causes = this. What HW/OS? Are these disk reads or writes? What kind of modules do you = use? PHP or no PHP? etc. I once observed really poor performance on a server during a load test = due to disk IO and associated wait-times. The IO operations were disk = writes which was bizarre because nothing was supposed to be written to = disk. It turned out being mod_ssl writing to the DBM-based SSL session = cache. After changing it to shm the problem went away... -ascs =20 -----Message d'origine----- De : Samuel Vogel [mailto:samy-delux@gmx.de]=20 Envoy=E9 : samedi 29 septembre 2007 17:09 =C0 : users@httpd.apache.org Objet : [users@httpd] Investigating high harddrive load Hey people, I would like to know if there is any way to debug what vhost is causing = the high load on my harddrive, that I'm experiencing. To be more specific: When I run "top", 80% of my CPU time is in i/o wait. How could I find = out, what vhost is causing this?
