Are ZFS ZIL / ARC slowing down my servers?

I'm using ZFS on 10u8, 10u9, and 10u11 SPARC systems.

My SAN has a lot of hardware optimization built in for caching reads/writes, staging LUNs across multiple tiers of storage, pre-fetch prediction, and generally a darn nifty bit o' storage technology magic.

My mind is thinking I can basically disable ZIL by setting all ZFS filesystems logbias to throughput, and set ARC primarycache to metadata only (or none), and secondarycache to none.

Could this increase performance of the filesystem and operating system due to reduced computational workload? Or am I missing something?

Any and all commentary is greatly appreciated.

Howdy, Stranger!
