ISPConfig is too slow

[csoky]

I made Perfect setup on my Debian Sarge. The instructions are really perfect! Congratulation to Falko!
Everything is works fine except one thing.
I installed ISPConfig. (with https). I could logged in. (https://localhost:81).
I can browse in menu of ISPConfig, but the browsing really slow or sometimes show error.
Same thing from other machine on the LAN.
Anybody have an idea what's wrong?
