The profile that led to this feature request took so long to load I gave up(around the 10 minute mark), killed the process, and reverted to a database backup(as I couldn't load it to delete it).
Now, I wanted to time how long it took exactly, so I set it up importing and started a stopwatch.
I specifically remember thinking "I should make sure to mention I don't have that option to generate command segment info on", but around the 35 minute mark I had a "wait a minute..." moment and checked the config file, which revealed that it was actually on(I must have swapped out the config going back through older versions in between).
After turning it off(I loaded another profile using the command line option to get VoiceAttack to load, though I could have modified the config file manually as well) the profile loaded in a ten-ish seconds.
So, perhaps that message should include a checkbox to turn off that option if it's on(it may be on for a specific profile that doesn't cause loading issues, which would be easy enough to forget).
