What are the actual Bittorrent trackers (announcer only, no web part) for a php site?

Question

bittorrent

There is a working torrent site. Web part (the site itself, directory) - self-written, in php + mysql. The scripts of the announcer and scraper are taken from here - opentracker and rewritten for PDO. Everything has been working for over a year now. BUT! It seems to me that the announcer is on http and even more so on http snot a very good idea. I look at some the announcer works on UDP (for example, on the rutor), and it seems to me so faster. And the announcer that I use has not been updated since 2009, i.e. as if outdated, and sometimes sprinkles with various errors. I could try to fix it, but I thought about changing it to something relevant. I decided to google which solution is better and more popular. I stumbled mainly on articles 10 years ago about XBT Tracker (XBTT), how cool, optimized and fast it is. And it seems that the functionality is right 100% what I need. But! I was disappointed when I found out that he, too, had not been updated for about 10 years. And this is also fraught with all sorts of errors that I can no longer fix, since I do not speak C ++. I continued searching further, came across mentions of TorrentPier, TBDev, TBSource and their modifications. But they are all bulky, along with the forum, and I absolutely do not need a forum! I also came across mentions of anotheropentracker , but it works without a database, which means I won't be able to display statistics in the web part. In general, I spent several days searching. Therefore, questions for the pros:
1. Announcer on which protocol is better? http, tcp, udp? It works for me now on https, and for some reason it seems absurd to me.
2. Better in php or not in php?
3. What are all the same relevant, without a web part?
4. Is XBT Tracker up to date? Does it still work? In terms of functionality, it suits me, but the update date of 2010 confuses me. Since then, MySQL has changed, and in XBTT, database queries can now be crooked.

Answer 1

I use it, it works https://github.com/WhatCD/Ocelot
In principle, xbt will work, etc. Nothing breaking the old did not seem to have happened in the protocol since those times.
It will only be difficult to compile, perhaps both xbt and ocelot.
I also found some fresh docker builds with a torrent server, but did not test it. Through Google, you need to search again, there, in theory, it should start from half a kick.
