'Processing' appears to be substantially written in javascript, a web based language. If the performance is not good there are several generic recommendations. The first is to stop using Chrome as your Browser. Chrome has never been optimized for Mac, and it requires far more computer resources than any other Browser. Use Safari or Firefox instead, and be sure to completely QUIT Firefox, and not just close all its windows (which leaves it running and consuming resources).
By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners. or a VPN that you installed yourself. The main reason is that they are relentless in scanning your files, non-stop, looking for virus-like patterns in Everything. When completed, they do it all again.

if those steps alone do not solve you issues, there are more steps that can be pursued, including Etrecheck reports. Consider downloading and running this little "discovery" utility, Etrecheck. it changes NOTHING.
it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed.
if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the system ClipBoard, then Pasted into an Additional text window in a reply on the forums.
