I developed an application for client that uses Play framework 1.x and runs on GAE. The app works great, but sometimes is crazy slow. It takes around 30 seconds to load simp

Google does not usually provide a contact support for a lot of services. The issue described about google app engine slowness is probably caused by a cold start. Google app engine front-end instances sleep after about 15 minutes. You could write a cron job to ping instances every 14 minutes to keep the nodes up.
