January 27, 20215 yr Hi , I installed unRaid 6.8.3 on a Thecus N5550. Overall I love it. BUT, the Thecus used to easily supply 113 MB/s in either direction when writing/reading. Now it will read at ~108MB/s, but writing is usually bouncing around 50-80MB/s. This is with a Samsung 860 PRO SSD setup as a cache, which seemed to make no difference in write performance. Why so slow? Do I have a setting set wrong? unraid-diagnostics-20210416-1431.zip Edited April 20, 20215 yr by Belgian Genius

You can test network performance with iperf3 (install it using the NerdPack plugin) and you can test disk read (not write) performance with the DiskSpeed docker container. Are you sure writes are actually going to the cache?
