Performance problem

[Nicolas Pinault]

Hi,

I've changed my server. I've installed Kallithea 0.3.3 on this new 
server and migrated my repositories from 0.3.1 to 0.3.3.
The new PC is faster than the previous one (10 years old). The new PC 
runs Windows server 2012, the old one was running Windows server 2003.
There is no other process running on the server that notably consume 
processing power.

This new configuration is much slower than the previous one.
Checking for incoming changes takes about 20s seconds.
Pushing is very slow.

Any idea of why I get this performance problem ?
