WinSer 2022 Slow file sharing
Hi, I have a problem with file sharing from Windows Server 2022.
The server is a new HPE ProLiant ML110 Gen10 with HPE Smart Array E208i-a and HPE 480 GB SSD 2.5" 6G Mixed Use SATA P18432-B21.
All FW are up to date, all drivers installed.
I have one folder shared on the server that should be accessible by the user PCs. If I copy data from the PC to the server, the transfer speed is around 130 MB/s.
If I copy data from the server to the PC, the speed is very slow. It climbs to 30 MB/s and then drops to 0 b/s. And it alternates like this.
iPerf from server to PC and from PC to server measures around 950 Mb/s.

Any idea where the problem might be?
- desert_lizardCopper Contributorcheck in to SMB and see what version you are running. winSAT will tell you disk speed but its not your disk. probably not the network either since your upload is fast. its something with the network protocol SMB most likely.
