It would be interesting to benchmark the >latter since all the recent VFS work. 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. ---MikeReceived on Sun Apr 24 2005 - 23:36:14 UTC
