    performance problems

    Hello, I have a strange problem in one of our servers that I think is related to the ZFS volume. If I run a du or ncdu command on this server to read the files, it is extremely slow. Takes about 30/40 minutes per TB. I don't notice the problem with writing to it. Before making the backup, our...
