I've installed Munin to monitor my debian (squeeze) webserver (2 x Intel Quad Xeon 4x2.66GHz, 16GB RAM, 2x1000GB HDD Raid). There are around 50k visits per day.
The scripts are very simple and there is a caching system with files to avoid too much mysql-requests. There are a lot of image requests. CPU is 99% idle.
I don't know if there are still enough resources to serve 100k visits per day or if I have to do something (e.g. change to nginx).
I added four images of munin which I think have the highest information value.

What I've done already:
- KeepAlive 2s (increased the memory load)
- Cachetime min. 1 week
- Compression is enabled
Is there room for more visits or are the server limits reached?
