pins on maps

Hi there

Can anyone suggest any ideas or options for speed performance enhancement on some new developments we uploaded this week on iHubbub.

The site has been been rebuild from scratch on a new updated commons platform with no panels [which slowed the old site down] and only necessary modules, but now .... with the new maps and pins feature it is far too slow [!] with the maps script and pin data but as this is now a vital hub of the site, we need to get this fixed asap.
