I have been using Parse.com for the last few months now.
I think Parse servers are now powering over 200,000 apps.
The service they provide is excellent, however i find their servers to be very slow, and therefore my app can get very slow to load content. I am surprised that they don't have a premium tier leveled model so that you can pay for a faster connection / server.
Can anyone recommend a good hosting / server provider for running a Instant Messaging type app?
Thanks in advance for your help.
