I have made myself a hosting setup following : http://www.howtoforge.com/multiserve...th-ispconfig-3
Now I have a problem with Apache2.
After a restart of Apache2 everything runs fast and nice but a couple of hours later it soooo long time to respond to http requests, after browsing a few sites it runs fast ??
I have not change anything in any config files regarding php or Apache2
Maby i need a cache plugin?
Check the global apache log for errors, especially vlogger errors.
Where is they stored?
Just to me sure...

Thats ok so far.
You should consider to install munin on your server o monitor all parameters to get an idea what is causing the slowdown.
Could it be something with the MySQL? is on a other server?
munin is installed and running...
After i installed munin it runs nice....???!!!!???
Well, tha wass a short pleasure.... :-(
Itīs the same, after some houers it uses several sek to load a page the first time, then it speeds up.
Is there a good cache funktion i can use?
Try to fine-tune Apache (for example, decrease KeepALiveTimeout to something between 2 and 5 seconds): http://www.howtoforge.com/configurin...um_performance
Also, please use a PHP opcode cacher like Xcache or APC.
If you web app supports it, you can use memcached and/or tmpfs ( http://www.howtoforge.com/storing-fi...ory-with-tmpfs ) to reduce disk I/O.
You should also check if you can fine-tune/optimize MySQL (for example, reading InnoDB tables is much slower than MyISAM).
