Optimal qlogic failover setting

We run a bunch of Oracle database servers using QLogic cards to our EVA 8100 SAN. We're trying to optimize our storage traffic, as we've been seeing some I/O slowness recently.

I've been wondering where to alter the ql2xlbType setting in modprobe.conf to optimize our load-balancing traffic. I know by default this is set to 1; are there any downsides to setting this to 2 or 3 instead? Any reason 1 is the default?
