High CPU load on idle proxies
I've been running Snowflake proxies for some time now and I'm seeing rather high CPU load even when proxies are idle.
I'm seeing CPU usage similar to this on all my proxies:
systemctl status tor-snowflake
● tor-snowflake.service - Tor Snowflake bridge
Loaded: loaded (/etc/systemd/system/tor-snowflake.service; enabled; vendor preset: enabled)
Active: active (running) since Sat 2022-03-12 11:18:37 CET; 1 day 5h ago
Main PID: 3242240 (tor-snowflake)
IP: 1.5G in, 1.5G out
Tasks: 9 (limit: 19046)
Memory: 55.6M
CPU: 7h 59min 35.486s
CGroup: /system.slice/tor-snowflake.service
└─3242240 /usr/local/bin/tor-snowflake
This corresponds to about a ~28% CPU load at an average speed of 15 kiB/s.
I looked at the CPU load over the timespan of a few days. I see a CPU load of around 30% even with no traffic whatsoever. Thus, I suspect there are CPU cycles wasted somewhere.
