How to improve performance with Global acquire lock enabled


I am writing with a question about the new Global Acquire Lock feature of Flowable 6.7.0.
I was facing an issue with my application that is using the Flowable BPMN engine which was poor load balancing of Flowable jobs between application instances.
With Flowable 6.7.2 and the global acquire lock feature enabled, that issue was mitigated but it introduced a huge performance impact for the app.
We were looking at a roughly 60% decrease in concurrent operation performance.

Is it possible, with some configuration or something else, to achieve similar performance as without the global acquire lock under load?
