The Caches on the Server is very slow. Yesterday copy from cache 1 to cache 2 (or the other way) was about 200 MB/s, today 400-500. Same speed with copy from and to the same cache. Bypassing the "user" copy from/to Cache1 was 1100 MB/s.
Parity has been running during these tests. That shouldn't influence the cache?
Cache1: 4 x nvme in Raid 10
Cache2: 1 x pcie ssd
Cache3: 2 x sata ssd in Raid 1
Cheers
