A good tool is the Task Manager (press Ctrl + Alt + Del and choose Task
Manager), in it you can see all the running processes and how much
memory/CPU they are eating. I've always got it running minimized to the
system tray, whenever things starts to feel sluggish I check the CPU-
utilization and which process(es) are using most of the CPU.
Normally high CPU will not make the system slow, just that specific
application, but if the kernel time is high also (above 10%) the system
will be slow. Another source of sluggishness is high disk-activity (no
good meeter exist that I'm aware of, but one can try to listen), if more
than one application needs to real/write a lot to disk they will be
slow. Disk-activity unfortunately also creates high kernel-times and
thus makes the whole system slow. The third thing that can slow down a
system is when the memory-usage exceed the available RAM, then the
system will start to page out which leads to disk-activity, plus that
you'll have to wait for applications to be paged in before they can be used.
