If you want to go as far as I did, run a lightweight kernel. No virtual memory or anything there, rock-solid repeatability.


I have googled it, but it appears you can not disable virtual memory in Linux. What kernel did you run?
What test metrics do you use for testing?


Lightweight kernel versions (one from Sandia Labs for one) for linux clusters don't do virtual memory. You don't disable it, it simply doesn't support it... I've been out of this for 1.5 years now so I can't tell you what is current, just that you probably won't want to run that on a general-purpose machine...
