iJumbo Posted November 15, 2021 Share Posted November 15, 2021 (edited) Hello, i experience very slow speed when transfering a big file from Server to a VM or any pc connected to the server. For example it starts at 1.3Gbit/s for a couple of seconds and then drops to 1mb/s or kb/s. The disk usage in the pool shows 1mb/s. This is reading from the disk and not writing to disk(ram) and it should be fast as the speed of the drive which is 130/180mb/s i don't understand. My guess is probably some files are still in RAM but if i transfer for example a 7GB Movie from server to VM or PC is 20/mb/s instad of 100+ Someone have any idea? Thanks. This is what iperf is reporting: Looks fast to me but the file transfer is still at 1mb/s / 20mb/s This what a transfer looks like: FROM Server to VM (using disk speed) Edited November 15, 2021 by iJumbo Quote Link to comment
iJumbo Posted November 15, 2021 Author Share Posted November 15, 2021 I'm gonna set the topic to SOLVED i figured out why: Used this configurations Set both MTU on vm and server to 9000 And the SMB2 config on samba Quote Link to comment
