Can I modify this plugin to reduce DB Queries?

Hello, I have this installed and really like it! The fact it notifies buddypress users when there’s new activity on their web browser. Either form friends or users they follow, it’s cool and I like it for a buddypress-desktop-notification addon. I like the way It mimics how Facebook works with pop-up push notifications. But, I’ve also noticed the queries to my Database has greatly increased after installing this plugin… Although, I’m not sure if this plugin is at fault, by sending too many request to the database per hour, or something else is causing it… If so, I’d like to modify the code of this plugin, lower the amount of times It queries the database per day, change it to It doesn’t query the DB than originally scripted. Any thoughts about this?

Does anyone know what I would need to do. to possibly modify, in order to reduce the amount of times this plugin queries the DB? Thanks for your help! Dan
