A starting point would be the generated log if the server is run
with GC_PRINT_STATS defined. (I'm not sure whether this works on
Windows.)  Also interesting would be GC_dump() output while it's
running slowly.

It sounds like you have a lot of compressed data stored somewhere.
If the gc is somehow scanning that that might explain the problem.
Is it stored in the garbage-collected heap?  It really shouldn't be
getting scanned either way.  (There is/was a known problem with the
gc scanning the malloc heap on Windows.  Hence I asked about Linux.)
