Why does the import need so hours?
Thats sucks so much.
The export to Google Earth need a llonngg time to.
THX!

no i try it on public transportAre you leaving vistumbler running for a long time?
to get people who run a Hotspot in the Car?For example, are you leaving vistumbler running overnight?
yes i keep running and it works. Maybe you can extend the visuals for out and input.Export to google earth will export all signal history if you have export the "Signal Map", so its possible this is what is slowing your kml export (if you have a lot of signal history)
1h on Public Transport and i got a lot of APs +1000.- For good performance I recommend a list size maximum of about 1000 APs. Above 2000 APs isn't recommended.

I had an idea for what may cause your long exports. do you see any access points that are active for your whole 1hr trip? If you do these access points may have a lot of signal history and take a while to export.1h on Public Transport and i got a lot of APs +1000.
