Users reporting slow performance after updating to Version 5.17.0

Background

Recently, ABP released version 3.22 which upgraded the bundled extension engine version to 1.1.1. AdBlock released version 5.17.0 which also updated the extension engine to version 1.1.1. We've had several reports of slow response time since the update.

It appears to be an issue in the extension engine since ABP, AdBlock, and the EWE test extension all seem to experience a similar issue with the 1.1.1 version of the extension engine.
