NFS/ZFS performance problems - txg_wait_open() deadlocks?
Hi.
System is snv_56 sun4u sparc SUNW,Sun-Fire-V440, zil_disable=1
We see many operation on nfs clients to that server really slow (like 90 seconds for unlink()).
It''s not a problem with network, there''s also plenty oc CPU available.
Storage isn''t saturated either.
First strange thing - normally on that server nfsd has about 1500-2500 number of threads.

Direct I/O ability with zfs?
We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs?
