Optimizing Linux memory usage
Too many system administrators still think that swap is bad. Too many Linux system administrators still also think that cache and buffer memory can be cleared without any problem whatsoever. There are even still Linux administrators around who think that virtual memory is the same as swap memory.
This talk is going to change your perspective on Linux memory management. You are going to learn how the Linux kernel uses different kinds of memory and distinguishes between active and inactive memory to decide what exactly to do with available RAM in your server. Based on this knowledge you’ll be able to profile your server’s memory usage and optimise it accordingly.
