Re: [Xen-devel] unusual domU memory performance

Interesting.  The system is running with a single AMD Athlon 64 3500+  
processor (note that both dom0 and domU are compiled as 32-bit  
systems).  There is a total of 2GB of RAM in the system, I have 1500  
allocated to dom0 and 256 to domU.
I had been contemplating this being an artifact of the system, but  
couldn't come up with any reasonable explanation in my mind.  It just  
seems off that if one program is being a resource hog, the other  
wouldn't speed up.  However, I couldn't help but wonder if this was  
somehow stressing Xen in such a way as to cause some unusual  
behavior.  Anyway, if it's not Xen, then I shall keep looking  
elsewhere :-)
Thanks,
