__latency__ of reads in a highly contested system (lots of reads from different processes ahead of you) OR the speed of light case (heres a read queues are empty fetch me the data if not from cache then disk, theres no contention). The former will improve for latency with fair queuing while SOL its true will incur a certain overhead yes. Again I would be interested to see if there have been mail threads / discussions around _intentionally_ not providing fair queuing in Solaris for perf reasons or if this something thats not been thought of so far. -- This message posted from opensolaris.org
