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.
For people reading this: tiernano has been super helpful on github & discord. Early triaging shows payload chose quic over TCP despite firewall disabled. Quic is a fallback and not yet CPU optimized, and struggles on windows (looks like a single threaded bottleneck - one core was at 100%). It appears payload jumps to the fallback too quickly, without giving TCP a fair chance first.
