Why mongoDb is slower than MySql in deleting documents? -


i doing tests databases performance. tried delete information stored database.

i've noticed mysql faster mongodb type of operation.

here results:

  • mysql time (in seconds): 163.724

  • mondodb time (in seconds): 221.150

queries used:

mysql: delete table

mongodb: db.collection.remove({})

in opinion, why happening?

structure of document in mongodb (version 3.2):

  • { "_id" : objectid("56a967615390f47f25798c97"), "user_id" : "1", "follower_id:" : "11" }

structure of row in mysql:

  • id=1 user_id=1 follower_id=11

operating system used:

  • os x el capitan; 2,5ghz intel core i7; 16gb ram
