@Robert P. we had the same issue, we had to work with the dev team to figure out the sweet spot for the garbage collection, how often it runs, the max load before it runs and the duration, Its alot like CPU wait time with VMware, You want to find that sweet spot where you have enough CPUs for the host but dont have too much where it is waiting for CPU to become available
