Hi,
In a performance test with Oracle (using files with direct I/O) it
looks like GFS is a factor 2 (!) slower than ext3. Can this be
true or should we be able to improve this by tuning etc.?
Tests are now done on a single node (of course the purpose is to
eventually use it in a real cluster using RHCS) and at this moment
we use GFS with lock_nolock. Both GFS and ext3 are used with iSCSI
devices (on the same SAN) and everything is done with RHEL4 and the
latest updates.
Thanks for any suggestions,
