The results are ... interesting. It seems that FreeBSD simply dies in
any test having a high context switch rate. Hmmm, this looks familiar.
Either I or a collegue of mine had a similar situation some time ago,
with the same discrepancy in disk speeds and the same difference in
context switches. Unfortunately, there was no solution.
How would one go about gathering data on such a scenario to help improve
this? We were planning a project involving VMware deployments with
FreeBSD 7.1 systems in the near future, but if performance is that bad
it is likely to be a show stopper.
Where do we start looking and who should we be talking to?
