Hi,
I'm a little baffled and am hoping someone can point me in the right direction. I have an older FreeNAS server I'm looking to replace with a newer TrueNAS core server. The new TrueNAS Core server is much better from a hardware perspective, but it doesn't perform as well as I think it should.
I used IoZone to test both systems and found my new server scores about 3x-4x better than the older system, that's about what I would expect. However, using sysbench to test random file io, the older system performs better in SMB, and about the same on NFS.
Both systems are Supermicro servers, I've included the specs and test results:
