I'm running on performance issues with WCF on mono.

On my Windows 7 box I can do about ~43K operations per second to my WCF
On the linux box it drops to less than 500 operations per second. 
That is as long as I try sending less than 1600 messages. 
When I try sending 1700 messages performance on the linux box drops to

I also tried opening and closing a connection for each message. 
Performance results were: 
    Windows=18000 ops 
    Linux=10 ops

The WCF service does absolutly nothing.
The server/client looks like: http://blog.shutupandcode.net/?p=1085

/Hardware Specs /
Both boxes have i7 with 4 cores and 8 threads and 16gigs of ram.
/Mono Version/
Mono JIT compiler version (Debian

Any ideas what is going on?
