I/0 delay snapshot

[monokeb]

I noticed in version 8.3 when a snapshot is taken, there is a very large increase in I/O delay, which has not happened so far in versions older than 8.2

Hi monokeb!

Could you provide further information about the I/O delay? It would be much appreciated if there are any indicators (e.g. logs) showing the increase in I/O delay, pressure or decrease in throughput. On what storage are the snapshots taken? Which hardware is used?
