- striking 6y agoI think this is true for any RDBMS, though. If your block device has high latency, you will see bad perf when the DB tries to fsync.
- tutfbhuf 6y agoBut the block device latency is usually a order of magnitude lower (microseconds) than the network latency between the database and its clients (milliseconds), except when all clients are located in the same datacenters.
- stefanfisk 6y ago”Network filesystems” means stuff like NFS. Networked block devices should generellt be fine AFAIK.
