I'm using no AV whatsoever. I guess Windows Defender could be a thing, but I have never run it either.
Also, for reference, my upload speed is usually around 100Mbps, but on butler i get around 300KB/s
And what speeds are you seeing when uploading via butler from your Mac Mini?
I'd really like to solve this issue but until I can reproduce it, I'm kinda stuck :(
That's fine, sorry if I'm being a bit hard to read.
My builds upload nearly instantly on my Mac Mini. So, about 50-70MB done in about 3-5 seconds.
