@0xERR0R I was looking at the package layout for these metrics. I was going to open a PR to improve performance by moving the metrics to package local use. This would also eliminate the need for a bunch of inter-package channels and queuing.

But, I'm not sure this architectural change would be accepted.

@SuperQ I'm not sure if I fully understand what you mean, but you can always create a PR with a proposal and we can discuss you solution. If it makes things more performant and simpler -> that would be great
