Alexander Motin 252f46be7d ZIL: Detect single-threaded workloads ... ... by checking that previous block is fully written and flushed. It allows to skip commit delays since we can give up on aggregation in that case. This removes zil_min_commit_timeout parameter, since for single-threaded workloads it is not needed at all, while on very fast devices even some multi-threaded workloads may get detected as single-threaded and still bypass the wait. To give multi-threaded workloads more aggregation chances increase zfs_commit_timeout_pct from 5 to 10%, as they should suffer less from additional latency. Also single-threaded workloads detection allows in perspective better prediction of the next block size.
