Meteor 1.4.2.5 Performance issue

Hi team,

Developed a Meteor+Ionic2 app based on the following example:

https://angular-meteor.com/tutorials/whatsapp2/meteor/setup

When there are more than 250 chat messages are there, it seems to be not displaying the chat list and getting blank page. But it works great if the chat count is less than 250.

Any help on this greatly appreciated.

Thanks.
