After the initial configuration and loading our existing map, the world was very laggy. Found this article about performance. It was very in-depth but one of the first thing I noticed was CPU. I add selected a VM configuration in Azure mostly based on price but then increased it for more RAM. I assumed CPU would be go enough at because it was a dual-core. But, as the article mentioned, there is a lot of calculation going one. I had already notice the time tick warnings.
So, I researched out to convert to a better VM. The VM had a 60% better CPU and used SSD storage. After the re-provisioning finished, I tested and it did seem much faster. The CPU usage stayed around 70%.
I had only selected one core CPU because it mentioned that Minecraft wasn’t multiple threaded. But, I decided to try re-provisioning to two cores and see the performance. In addition to Minecraft, Windows can take advantage of multiple cores so it will spread out the processes.
I did a quick test after this change and the performance of Minecraft seemed much better. The CPU utilization was about the same but spread over both cores.
