Slow performance on MongoDB SRP site

The getCount calls used by pages loading comments are very slow due to missing compound index.

Resolution

Log in to Mongo shell or another mongo shell tool such as RoboMongo.
Access the SRP database, for example, the shell command use:

use aem-msrp
Run this MongoDB shell command against the database to create an index in the background:

db.content.createIndex({ parent_id_s: 1, base_type_s : 1 }, { background: true })

Bemærk:

Make sure to run the command during low traffic hours as this creates the index while the system is in use. For more details on background index creation, see MongoDB docs.
