Thread:Extension talk:FrequentPatternTagCloud/Maximum execution time

I have just run Special:FreqPatternTagCloudMaintenance for the first time after installing the extension. I get:

"Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\www\gdmwiki\includes\db\Database.php on line 726"

is there anything I can usefully do to avoid this?

I can use Special:FreqPatternTagCloud, but I guess the results aren't correct, until the maintenance page runs succesfully.
