Hi to everyone!

I'm using CSFLE with Mongoose (Mongo Driver 3.6.3) and MongoAtlas (tested on M1 or M2 plan). 

I follow your guide at this link.

Data are encrypted and decrypted automagically as expected.

Performance drops with CSFLE enabled, sometimes 5x slower, sometimes 10x slower, 20 in the worst case.

Even worse, my app become unresponsive because every communication with Mongo timed out.

I try to understand what mongodb-client-encryption do but I can't spot any clue. 

Someone can you help me?
