Controller Performance vs Database Size

Troubleshooting


Problem

Customer would like to know if there is a link between the size of the Controller application repository database and the speed/performance of Controller.

Symptom

Customer is experiencing slow performance in Controller, and would like to know if reducing the size (compacting) the database will help.

Example:

A typical (average) customer’s Controller SQL database (after being in production/use for a small number of years) will be approximately 10Gb to 40Gb in size

  • However, the largest size of a customer’s database that the author has seen is approximately 160Gb.
