in both cases, I transferred a single ISO. one was 1.7GB (Mac -> PC) and back it was 6.5Gb (Win -> Mac). CPU seems to be quite low... PC is hovering around 11-14%, it's usually at 10% (got some VMs running in the background). Agent on the mac is around 4-5. Just ran a second test today, and got less than 5MB/s from Windows -> Mac. The numbers for CPU and RAM above are from that run. 6.5GB ISO is being sent again... [Edit] There is a pending reboot on that Windows box I need to do, at some stage, and I will retest it then. I double-checked that it wasn't sent data over Zerotier or Tailscale (both installed on both machines) and nope. It's just over the standard LAN. Both boxes are on the same subnet, so nothing between them. I will do a bit more digging and open a ticket with my findings. Thanks.
