For some reason the speed when installing via docker is not more than 200 mbps, and also why 2 reverse proxies nginx and caddy?
how to solve this problem?
I suggest you try to narrow down where the slowness is coming from. Maybe try using iperf to test the network speed in and out of your container, watch top to see if you hitting max CPU, that sort of thing.
I think the most likely cause is the container’s access to the disk being slow. One of the ways that docker really complicates a setup is that docker comes with a complicated set of options for how it stores and accesses data. I haven’t actually messed with these options in docker since I decided to use podman instead, but for podman I had to specifically enable the “overlay” storage driver to get decent performance.
