After perusing the OOW'03 presentations, I see that Win Coekaerts' presentation says "IO throughput [on OCFS] is equivalent to RAW IO". Has anyone seen this behavior? It's entirely possible (probable!) that I didn't do something correctly, given the bastardization I needed to do (installed on RH9 because AS2.1 won't support our hardware), but I saw OCFS performance about 40-50 times slower than RAW (rough estimate).
I didn't implement the OCFS fileutils as I wasn't going to manually do anything with the files. Surely the oracle binary doesn't call dd, cp, and mv directly for it's file management and data I/O, does it? Is it the "comm_voting=1" in the /etc/ocfs.conf file? Or is it more likely to be async IO (my guess)? Or a combo? Anyone with experience on this? Anyone attend Mr C's presentation?
