INFER runs too often and has a massive impact on the system

Steps To produce

1. Create a Cluster
2. Load documents
3. Open QWB

Problem

• INFER is taking over 10 seconds and in some cases it is taking over 10mins.
• Fills the complete_requests can't debug slow queries from the application
• INFER seems to be blocking other queries from running

I suspect the problem is large not binary documents

Expectation
For INFER not to have a big impact on the system
