High CPU usage

[ASTRELION]

I have a small lobby server that is just an island floating in an empty world that idles (no players in the world and paused) around ~2% CPU usage. I gradually added plugins to this server one by one, restarting and monitoring for each, and once I added Interactive Chat, CPU usage now idles around 15%. Removing just Interactive Chat drops it down to the ~2% it was previously. This is with the default plugin settings, no tweaks. This behavior is also observed with no other plugins added except for Interactive Chat and its dependencies.

Is this normal? Is there just a setting I'm missing? This obviously isn't a deal breaker, but it is quite an increase in CPU usage for a single plugin, especially since no one is even chatting or connected to the server.

I'm not sure what other details are useful. I ran the Spark profiler, and no plugins (including Interactive Chat) had noticeable impacts to performance according to it. I see no errors in the console, and the plugin behaves as expected.

Server details:

• Paper 1.21.8
• Server runs via Aikar's flags
• Running behind a Velocity proxy (no plugins or extra configs)
  • No other servers are connected to the proxy
• Pterodactyl panel for management

Seems to be fixed with the latest release.

Actually, 4.3.3 seems to fix the issue for Papers servers, but not the Velocity proxy they all are on. My Velocity proxy still uses ~15-17% CPU on idle, compared to ~1-2% idle with no Interactive Chat
