With Parse server 3.0.0 everything is going fine, while with Parse server 3.1.1 & 3.1.2 (I haven't test with 3.1.0) count operations are very very slow. It's immediately visible in Parse Dashboard, as the dashboard tries to display the count of each class (we have around 15 classes plus the parse ones), and it fails to do it, with most requests ending in timeout (especially the ones for the 'big' classes with more than 5M rows). To be more precise, with Parse Server 3.0.0 those counts appear instantly.
Steps to reproduce
Open the Parse Dashboard on a server with 3.0.0 and compare it with a Parse Dashboard on a serveur with 3.1.1 (and lots of rows)
