Yes, this is an open problem. I hoped to fix it by using threads in
Tramp, but this has other problems.

Great! Since you are a regular eglot+Tramp user, could I ask you for a
test?

I assume you are using Tramp with ssh or scp. If you also don't use a
password (for example via public key authentication), please try the
following setting:

--8<---------------cut here---------------start------------->8---
(add-to-list 'tramp-connection-properties
             (list (regexp-quote "/ssh:user@host:")
                   "direct-async-process" t))
--8<---------------cut here---------------end--------------->8---

"/ssh:user@host:" must be adapted of course, and you must set this prior
opening a connection to this remote path. This should give you better
performance when starting the language server.

Does it work for you? Does it make a difference?
