I’ve been trying to figure out if it’s better to run ASM on Linux using ASMLib or raw devices. Some of the Oracle documentation claims ASMLib gives better performance that raw devices with 10g Release 2, while other sources claim it only affects candidate disk discovery time…
Whilst setting up a test I wrote this article:
ASM using ASMLib and Raw Devices
I’m sure the configuration information will be useful to others, but my first performance test only convinced me that using VMware on my kit at home is pointless for performance tests. You don’t say!!!

Did you ever decide whether performance claims could be substantiated? I’m very curious, and writing a blog post about it right now…

I’ve never had good enough kit to perform proper performance tests. Using VMs on a desktop isn’t really a good test.
