performance - How do I optimize the OS for SSDs? - Ask Ubuntu
WebWhen writeback is executed asynchronously (e.g. for compression), bios are bounced to and issued by worker pool shared by all cgroups. This leads to significant priority inversions when cgroup IO control is in use - IOs for a low priority cgroup can tie down the workers forcing higher priority IOs to wait behind them. WebBtrfs also isn’t the sole area where Linux was needing improvement in the storage area. For example, writeback throttling was significantly improved a few years ago. This example improves the memory management, making Linux more able to handle the mixed database and archival workload mentioned above. Not to say that all errors are fixed.
