[Xen-users] Xen benchmark

[Christiaan Ottow <chris@xxxxxxxxx>]

Hi all,

I've performed a benchmark on my server to compare performance with  
and without Xen, and with and without domUs active. I used lmbench to  
measure basic  hardware operations on math and memory, and system  
calls like mmap(), fork(), exec().
The results are at http://drainbamage.nl/2009/04/05/xen-benchmark/ .  
It seems that Xen adds significant overhead to process creation  
routines (fork, exec) and mmap and page faults.
However, I'm no OS expert, and I'd like your guys' feedback on the  
numbers and my interpretations of them. Does Xen really add these  
latencies (or is my setup messy), and what is their impact in real life?
Best regards,

Christiaan Ottow
