Hello
A friend of mine is running a LAMP (PHP, MySQL, Apache,
Debian) Web 2.0 site on a dedicated, hosted server with about 300
connected users when it's really busy.
The server is an Intel Celeron 2.4 GHz with 1GB of RAM, a 40GB IDE
drive, and a 10Mbps bandwith.
Here's what top says:
Tasks: 196 total, 6 running, 181 sleeping, 8 stopped, 1 zombie
Cpu(s): 71.6% us, 8.6% sy, 0.0% ni, 58.0% id, 0.8% wa, 0.3% hi, 0.7%
si
Mem: 1023656k total, 963348k used, 60308k free, 119612k buffers
Swap: 514040k total, 0k used, 514040k free, 484324k cached
The site is too slow in the evenings, but we don't have the skills to
check why and what can be done about it.
For all you LAMP experts out there: What things would you try to see
where the bottlenecks are? Is there some kind of check-list that we
could go through?
Thanks for any tip!
