How about about creating a job queuing system to handle the long running database queries. You will have to break it down into steps: User initiatives Query via AJAX call. System receives query and adds it to queue, return status of 'Added to queue' System daemon monitors job queue and runs / records status / stores results of jobs. Background process on web page monitors job status via AJAX calls and alerts user when complete. On linux systems, The pear module 'System Daemon' is very good for job queues and easy to install: [http://pear.php.net/package/System_Daemon] Hope this helps.
