Direct I/O Performance v5.1
2002-10-30 12:51:05
Hi everyone.
We're planning to upgrade to 5.1 in about 5-6 months. I was wondering if anyone
has done any performance testing with the direct i/o option?
I have seen marked improvements in storage pools when using jfs volumes and
read-ahead vs. raw volumes. Has anyone done any tests with jfs/read-ahead vs.
direct i/o?
Thanks.
