@bi4smooth Hello. Thanks for your answer. I'll look for options/settings about cache, but transmission is quite simple. I download large files from other trackers, much larger files and also more files per torrent. Never happened this. I have this behavior in two computers, both using Mac OS (Mojave) and Transmission (3). After posting I downloaded utorrent (which I would love to avoid, seems it was once a good client that became a bad player) and it seems to work perfectly (or at least with a healthy/usable variation). Connection does not drop to 0, although it fluctuates. I'll try to investigate a bit more, but it seems transmission might be nor playing well with this site, no idea why.
