3P: Program, Process and Processor. When all 3 are at their best, Magic happens 😁😁 😁. A well written code and optimized program can leverage the full potential of kernel and hardware. This can create a synergy that can lead to optimal system performance allowing fast, reliable and efficient computing. The above can achieve the maximum possible throughput. It takes years and years to understand all 3 and implement accordingly. And here comes the 4th P: …Pushkar Kumar

Ever Wondered why we had Paged and Non Paged Pool in memory section besides cached and in use memory! In-use - refers to the actual amount of physical memory being used. Cached - Refers to the amount of physical memory being used for speeding up file system access. On client OS, up to 10% of your memory is used for buffering writes ("dirty page threshold"). Paged pool - it is the amount of kernel and device driver memory that CAN spill over from physical memory into the slow page file Nonpaged pool- it is the amount of kernel and device driver memory that must stay in physical memory. This type of memory cannot be offloaded onto the disk.
