Hey guys,
I know it's hard to compare apples to apples when you start talking about performance and hardware but I would appreciate some feedback. I am currently have a 32Bit HP Proliant DL380 with 2 2.8Ghz cpus and 4G of memory running Fedora 10. At present I have 150 hosts generating between 10-15G worth of logs per day. I dump all of my logs to a Mysql database so that I can use php-syslog-ng. The OS is build on a 1.2T raid 5 disk array. To cut down on I/O I have the database writing to a ext3 filesystem while the rest of the box uses LVM. I have mounted the database partition with noatime and implemented all of the mysqltuner suggestions. My box is performing slow like molasses.

It isn't good that you are swapping. Though it isn't much at this point. Is there a memory leaky application on the box? What is the uptime of the box? FWIW, I generally don't consider ext3 to be a *fast* FS. -- Matt Zagrabelny - mzagrabe@d.umn.edu - (218) 726 8844 University of Minnesota Duluth Information Technology Systems & Services PGP key 1024D/84E22DA2 2005-11-07 Fingerprint: 78F9 18B3 EF58 56F5 FC85 C5CA 53E7 887F 84E2 2DA2 He is not a fool who gives up what he cannot keep to gain what he cannot lose. -Jim Elliot
