Hi everyone!
I recently successfully traced some network issues I was having in Counter Strike back to my QBittorrent client having too many open connections. Global maximum was set to around 500, with a 100 max per torrent. This caused major jitter and packetloss in-game.
My current router is an Asus N18U which has Asus-Merlin on it.
The issues kept coming back even with a smaller number of open connections to the point I had to shut down the client.
I can’t remeber having these kinds of issue on Windows (current system CachyOS wit latest kernel), but I can ne wrong.
For what kind of specs should I be looking in a router for this kind of task? Would a MikroTik hEX refresh (upgraded RAM and CPU) be enough or overkill?
Thanks!

You might (read: likely) have traffic shaping upstream of you doing something as well. You can test for that at sites that measure buffer bloat.
In that case, you can implement some kind of queing management like fq_codel to help with this.
I alteady did that and the site measured an increase somewhere between 20ms and 50ms, but in-game it would frequently go up to +100ms. I have almost no onowlegde in the domain of networking, so going for a hardware solution is easier in my case.
