This was on hardware using the 3ware driver which is essentially the same 
on RELENG_4 and RELENG_5. I also tested IDE performance which gave similar 
results (i.e. RELENG_4 and DragonFly was better), but the drivers are 
different so its hard to gage if thats a driver issue or not.   I am not 
sure if any of those tests answers your question, as I am not sure how to 
answer it.  I was looking for a way to measure overall throughput that 
samba, NFS, database and imap servers could do either on RELENG_4 or 
RELENG_5 as we start to migrate various servers from RELENG_4 to RELENG_5.

I have a faster disk subsystem I can test against (Areca SATA RAID) that 
works on RELENG_4,RELENG_5 and HEAD and could re-run the tests varying just 
the base OS.  If there is a particular test you feel best simulates disk 
performance, I am happy to test.
