Aggregation takes time with large collections

[fashkl]

I'm using the package in many places in the project, it is working perfectly with all collections with med size, once i use it with little bigger collection more than 36k doc, it takes some time till finished more than '8 sec' and the pipeline is not complicated 'only simple match', can you please help to figure out this issue if anyone faced that before.

MongoDB server version: 4.0.6
Meteor version: 1.8.1

A bit late to the party, but i'd make sure that I have the required indexes for that simple match.
