Alexander Motin 23fad19818 Reduce zfs_dmu_offset_next_sync penalty ... Looking on txg_wait_synced(, 0) I've noticed that it always syncs 5 TXGs: 3 TXG_CONCURRENT_STATES + 2 TXG_DEFER_SIZE. But in case of dmu_offset_next() we do not care about deferred frees. And even concurrent TXGs we might not need sync all 3 if the dnode was not dirtied in last few TXGs. This patch makes dmu_offset_next() to sync one TXG at a time until the dnode is clean, but no more than 3 TXG_CONCURRENT_STATES times. My tests with random simultaneous writes and seeks over many files on HDD pool show 7-14% performance increase.
