Seems to have done the trick, also needed to increase the number of
file descriptors to handle the extra helpers.

At peak load now using 33 (30 was our Default), what i can only assume
has something to do with problems related to queuing theory and
exponential wait times occurred due to this.

Hopefully this helps someone in the future.
