Then, click Erase at the bottom to format the drive. The operating system will initialize itself, configure the system hardware e.

Operating system performance issues commonly involve process management, memory management, and scheduling. The other factor that made memory compression systems lose their popularity was the performance issue. Memory compression algorithms took a hefty chunk of processing power. That meant that while they let you get more done with less physical RAM, they tended to bog down your computer when they needed to compress or decompress memory.

Memory compression is making a comeback, primarily because of the advent of inexpensive multiple core processors. When the routines used for memory compression can be offloaded to one of many processor cores, you're not likely to notice any performance hit when memory needs to be compressed or decompressed. It simply becomes a background task.
