I've been lurking in listen-only mode since I don't know the netconn API.
The PC is sending as fast as it can, but the device is synchronized to
the storage speed, so incoming data needs to be buffered and eventually
slowed down, and that is what TCP tries to do.
However, your packet loss is a

That's not really true. You had to upload the files because noone wants
to load ~300 kByte into their mail inbox just because you're too lazy to
strip down

I think it's a processor speed issue. Lost packets could be an lwIP

Yes, I noticed but did not know what to make of it. I now disabled this
offloading feature and have a new capture, attached to this mail.
