7 years ago Yeah, what happens is that those pieces, (2180, 1844, 244 ...) are already being requested but the replies for the data has yet to come back from other peers. I have been thinking of having a timeout for piece request replies but there's probably a better solution out there than just flat canceling pieces that have yet to return. peices SHOULD be cancelled when a connection times out.
I think that it also may be due to that revision using a channel for sending, the latest versions use a mutex which prevents bufferbloat when using a channel which forces messages be sent in order instead of whenever they are able to.

Endless squirts of this appear.

The above version still has problems with download speed, and piece selection seems to level out after 20-30 minutes. When restarting XD, the number of pieces downloaded increases again, then gradually decrease over time.
