Hi Fabien,
> Sure, it definitely makes sense to reduce the overhead when the extension is disabled. I wanted to understand the source of performance issue, and your explanations where not enough for reproducing it.
Thanks again Fabien. I am attaching the patch to this email in the hope of getting it approved during the next commit fest.
I will continue trying to find a simple performance test to exemplify the performance degradation that I have seen with more complex workloads.
