Hi Michael.

Here are the diffs from the xcscope.el from the cscope-15.6 source:

It seems as though xcscope is starting a new remote cscope process for
every query. This adds 10 to 20 seconds to each query, on top of the
time it takes the remote cscope to do the lookup, which is already
about 15 to 20 seconds. I changed my ssh setup to no longer require
passwords, but it still incurs these delays.
