Optimzing a server for hosting applications
| Posted by shmget, 02-02-2010, 01:21 PM | | I have a low end dedicated server, and I'm trying to see what performance tweaks I can use to squeeze extra performance. There isn't any real need to do this, but just wanted to see how much I can get from a minimal configuration.
I have 512MB of RAM, and a 2.4 GHz Celeron. The disk is IDE, not SATA.
I installed nginx, spawn-fcgi, and php5. I installed Wordpress with the Athualpa theme. I turned on the performance stats footer, which indicates how many queries and the processing time.
I started out with a rendering time of 0.6 seconds with 231 queries. I installed eAccelerator and this went down to about 0.3 seconds.
All programs were compiled from source, and the server is running FreeBSD 8.0. I compiled mysql server with the optimizations and static executable options.
Are there any other settings I can change to make the rendering time faster?

There's always something you can tweak A lot of the times though, it comes down to where you're experiencing problems. You should also check out the man pages for iostat, vmstat and mpstat for CPU, disk I/O and virtual memory statistics. This should shed some light onto which components of your system are bottlenecks.

If you can indicate the site address, people can point out any simple improvements that can be made.
One person running a large web site on high-performance dedicated servers was very, very surprised at the difference some simple web page tuning made.
