It does not appear to speed up when restarting the program. It has gotten 
slower since when I first installed it over time.

Is the slow down across one session i.e. does restarting the application
cause it to speed up again?

You can eliminate worked B4 and country name lookups as a cause of slow
downs simply by turning the feature off in the settings. I would be
fairly surprised if the lookups are the cause since they use logarithmic
complexity searches for the big ones rather than linear and should scale
well with logbook size.
