What's 'iostat -xn' showing in the asvc_t and %b columns? Isn't some disk taking an excessive amount of time to fulfill I/O requests? For example one of the disks in the pool showing 100% busy and very large service times can slow down the whole raidz and by extension the pool (all blocks read from the raidz will incur a significant hit).
