Linux Server Lag Savior: Release Cache Memory to Boost Performance by 30%

To speed up operations and reduce disk I/O, the kernel typically caches as much memory as possible, which is known as Cache Memory. By design, pages containing cached data can be repurposed as needed (for example, by applications). Cache memory is not automatically released after a program finishes running. This can lead to a situation … Read more
