Handle_path high cpu

[spekkio]

Hello! So I’m running Caddy2 to reverse_proxy https://octoprint.org/ and GitHub - jacksonliam/mjpg-streamer: Fork of http://sourceforge.net/projects/mjpg-streamer/. Works great for octoprint, however whenever I use the /webcam path, cpu on spikes to 50%+ on one core.

*.example.com {
    tls {
        issuer zerossl {
            disable_http_challenge
            disable_tlsalpn_challenge
            resolvers 1.1.1.1 8.8.8.8
            dns cloudflare <key>
            }
        }
    reverse_proxy localhost:5000
    handle_path /webcam* {
        reverse_proxy localhost:8080
    }
}

While directly connecting to GitHub - jacksonliam/mjpg-streamer: Fork of http://sourceforge.net/projects/mjpg-streamer/, I see about 2-4% cpu usage on one core.

Note that I am running caddy v2 on a raspberry pi 4b 8gb, so perhaps arm64 is coming into play here? Either way, I’m surprised cpu spikes that much, though mjpeg does make a lot of requests. Do you think this is normal? Is there any optimizations to be had here in my config? Thanks!
