When Windows 95 or NT runs out of memory, it simulates more memory by using the free space on your hard drive. Swapmon will let you observe your swapfile usage and see what applications put a strain on your RAM. It also shows you how to improve your system's performance, and lets you tweak the disk cache and free more hardware RAM for system use. Its analysis can help you decide how much RAM you should purchase if you decide to upgrade.System uptime is also displayed.
