Performance: multiprocessing improvement: step 2 (#6986)

* Refactored queues to use faster_fifo instead of mp.Queue

* Refactored LimitedQueue to include a counter for the number of items in the queue and updated put and get methods to use the counter

* Refactor app.py and util.py to use a custom Queue implementation called LQueue instead of the existing Queue

* Refactor put and get methods in LimitedQueue to handle queue size and blocking behavior more efficiently

* code format

* remove code from other branch (merging fuckup)
