I think opening the thread with C-U RET instead of RET does exactly
that, i.e. only shows the matching messages.

In less extreme cases, using tree view (ALT-RET) may be an option since
it does not have to format the contents of the entire thread.

I have a vague recollection that someone pointed out that it is the
indentation that takes most of the time and that turning off indentation
speeds up the display of huge threads.
