32MByte / sec. So.. Python3 and 200ms latency results. This facinating mistery deepens. Please make a profile print with human readable [threadname printouts](https://www.google.nl/search?q=thread+profiling)

hmmm. so the lower non-script table is all Tribler?

impressive exploration. Good steps to the final goal: Tribler becomes latency tolerant, add big buffer, and remix anon tunnel packets.

_please read_ [Two Cents for Strong Anonymity: The Anonymous Post-office Protocol](https://eprint.iacr.org/2016/489.pdf) "AnonPoP offers strong anonymity against strong, globally eavesdropping adversaries, that may also control multiple AnonPoP’s servers,even allbut-one servers in...

Todays conclusion: Tribler drops factor 40 in performance when latency is added between single seeder, single downloader (tested with 4GByte file and 200ms latency). Factor 25 drop with pure Libtorrent...

@captain-coder remarked that touching Python at all from non-Twisted thread will cause trouble. Possibly the thing you see.

so uTP is enabled, but lt.fingerprint(*fingerprint), flags=1 what does that do?

 Please consider at some point to open up the magic box and dive into these detailed networking statistics. Something is off...

Key problem: ```discover why Tribler has 2.5 MByte/sec performance with 200ms seeder-leecher latency, and clean Twisted-wrapped Libtorrent has 16MByte/sec```. The methodology is to strip the Python wrapping code and use...

possible experiment to decide if the bottleneck is within the code or parameter settings or both: - Tribler stripped Libtorrent manager, which can only resume download - Libtorrent manager in...
