🧹 [Maintenance]: Add Parallel Benchmarks

[efectn]

Maintenance Task Description

Current benchmarks are enough to see performance difference of any code changes. However they do not meet all requirements of real-world benchmarks.

Since we are running benchmarks sequantial, the benchmarks do not get affected by mutex or other concurrent blocker events. And this may cause not to see drawbacks of some code changes on benchmarks. This is why we have to add parallel benchmarks, especially for performance-intensive sections like router.

Impact on the Project

It will make code review easier to see performance impactions of mutex etc.
