Hi, Fariborz. Several days ago there was a discussion about it. "NONE" or "WRITETHROUGH" must be used when possible. WRITEBACK may be used __ONLY__ if you don't care about data loss, e.g. ephemeral VMS which destroyed upon the crash.
Add more RAM to VM, implement bcache or LVMcache, add more drives, use SSD, NVMe and forget about the games with stuff above. ср, 13 мар. 2019 г. в 11:19, Fariborz Navidan <mdvlinqu...@gmail.com>: > Hello All, > > How does disk caching affects the VM's performance?
