Not really an answer to your question but here I never had 
speed/responsiveness/memory issues with transmission (Xfce, 16Gb RAM, 
50Mbit/s network bandwidth ):

[I] net-p2p/transmission

      Available versions:  3.00-r1^t (~)3.00-r4^t **9999*l^t 
{appindicator cli gtk lightweight mbedtls nls qt5 systemd test web}
      Installed versions:  3.00-r4^t(01:14:38 PM 05/29/2022)(cli nls 
-appindicator -gtk -lightweight -mbedtls -qt5 -systemd -test)
      Homepage:            https://transmissionbt.com/
      Description:         A fast, easy, and free BitTorrent client

I use it without GUI (-gtk -qt5) because I find the web interface just 
fine. Also, being server-based it runs regardless of who's logged into 
the PC, which is a plus here.
