This strategy is very successful in making a performant and responsive application, but is not desirable on Virtual Machines or hardware with few CPU cores. Pleroma instances are often deployed on the same server as the required PostgreSQL database which can lead to situations where the Pleroma application is holding the CPU in a busy-wait loop and as a result the database cannot process requests in a timely manner. The fewer CPUs available, the more this problem is exacerbated. The latency is further amplified by the OS being installed on a Virtual Machine as the Hypervisor uses CPU time-slicing to pause the entire OS and switch between other tasks.
-More adventerous admins can be creative with CPU affinity (e.g., *taskset* for Linux and *cpuset* on FreeBSD) to pin processes to specific CPUs and eliminate much of this contention. The most important advice is to run as few processes as possible on your server to achieve the best performance. Even idle background processes can occasionally create [software interrupts](https://en.wikipedia.org/wiki/Interrupt) and take attention away from the executing process and latency spikes and invalidation of the CPU caches as they must be cleared when switching between processes for security.
