vmswappiness

When running a specific workload on a Linux server, one of the key aspects you might want to optimize is memory usage. In Linux, the vm.swappiness parameter controls the degree to which the system favors swapping memory pages out of physical memory to increase the amount of free memory available. Adjusting this setting can significantly affect system performance, especially in a resource-intensive environment. Q&A: Tuning vm.swappiness for Specific Workloads A1: vm.swappiness is a Linux kernel parameter that controls how much the kernel prefers swapping to keeping processes in physical memory. It's a scale from 0 to 100, where a lower value means less swapping is done, and a higher value means more aggressive swapping.
