Hello guys, sorry for my poor English.
I just built a server with Xpenology(synology) on C612 motherboard, 40G nic, 2 x samsung PM1725a 6.4T nvme pcie ssd(2 x basic no raid)
just in case some ppl don't know it yet: We now are able to use nvme ssd as storage in synology (by using mdadm in ssh)
I expect that I could get 3GB/s speed from this server, but I failed. It only runs at 1GB/s.
I first thought its NIC or Network problem, but when I try to copy from one ssd to another ssd internal (on the synology webui), it also around 1GB/s, so I think its a internal problem.
Does anyone know any clue for my problem? I checked CPU(E5 2650L V3) usage when copying files, its about 16%, but if copying file can only use one thread of CPU(not sure), then I guess its CPU bottleneck? Is there a way to check each thread usage?
