Does the problem only happen when you play music ?
I've seen that some operations in my plugins are a lot slower if
executed the same time as music is playing, the main reason for this is
probably that it likes to prioritize streaming before answering plugin
requests.
Maybe the same situation also happens when Whitebear accesses the CLI
interface ?
Does it work fast if you disable all third party plugins ? If I
understand you correctly, it was slow also with plugins disabled ?

I think Squeezebox Server is single threaded, so it depends on how the
different CLI commands are implemented. So I think it can handle
multiple CLI calls if they are implemented in an asynchronous way, for
example if they are doing a HTTP call and waiting for a response.
Database accesses are typically not handled asynchronous so to database
calls that needs to access the database will typically be serialized.
In my experience, playing music will affect the performance, so the
first thing I'd try is to see if it behaves the same with and without
music playing. If it is slow only when music is playing, there is
probably not much you can do about it than change to faster server
hardware.
Regarding Custom Skip plugin, it only executes once at the end of each
track, so it feels strange that it should cause these problems.
