There is a big improvement in RHEL6. I was able to do a test where I had a large database that was being built in one VE by doing:

zcat database.sql | mysql database

I ran it on an Intel i7 machine with 24G of RAM, RHEL5, and it would lock up IO in the other VEs (they would just wait). I then moved the VE to a machine with identical hardware running RHEL6 (scientific Linux), did a repeat, and there was no impact on the other VEs. You couldn't even tell it was running.

I have other issues with RHEL 6 right now, specifically a strange routing issue, but in this respect, it is a big improvement.
