OK. The fluctuations are indeed strange, but do not look dramatic. Hope the test is representative for the issue.
One more not checked thought: right now we have some customer with pretty fragmented SSD pool, which spends significant amount of time in opening new metaslabs, that dramatically affects the performance. There are still attempts to analyze it better and address with some tunables, but it makes me think that having several metaslabs open same time may require proportionally more time to open/close them. -- You are receiving this because you are subscribed to this thread.
