@george1421 That’s right. In my case, with VMD enabled, there is no need to plug in any usb storage device in order to get normal throughput.

Upgraded to 1.5.9 and same behavior: fast with vmd on and slow with vmd off.

I don’t know if this helps but, after some testing, writing speed looks good and the slowlyness seems to occur only when copying from server, but testing network the bandwith looks good too.

One thing that pictures don’t show is that, with vmd off, rsync freezes for a while (even a few minutes) before starting or at the beginning of the copy but not with vmd on. I tried to copy with scp and it hangs too. Locally rsync, cp or dd from /dev/zero work well.

@sebastian-roth Yes, the USB key workaround works for me too with VMD disabled (but I had to use a usb3, with an old usb2 didnt’ work).

Anyway, I’ve been doing some write testing with dd and rsync from a debug task, getting same speeds in both VMD modes.

Sorry, I didn’t notice before that you suggested to upgrade because of partclone version. I’m using 0.2.89 too (FOG 1.4.4), so I’m going to get the latest and try again.

Thank you

Same problem here but solved (I think). Same model, same extremely slow cloning performance with 5.10.12-e1000e-3.8.7 kernel and same workaround with usb device connected (pendrive, but not other like mouse). Solution for me was enabling “Storage Controller for VMD” under “System Settings” menu.

I’m pending to test another laptops, only got one yet, but tried twice and looks to be working as spected (5-6 GB/s while enabled, 45MB/s while disabled).

Congrats and thank you very very very much for FOG.
