昨天 pbs 出了 4.1.0 版
release note 有一點 感覺有點有趣
Allow to control parallelism of verify jobs.
Backup snapshot verification is both an IO- and CPU-heavy workload, as it needs to read chunks from disk and verify their checksums.
The number of threads used for reading from disk and for checksum verification can now be customized.
In some setups, customizing the number of threads can significantly decrease the overall runtime of the verify job.
升級後 跑了一下 竟然省了一半的時間
該期間cpu使用率如下
預設是 read 1 verify 4
找時間再來調大看看會不會效果更好
