"Moo0 SystemMonitor lets you keep your eye on system resource usages of your PC. It currently supports 34 kinds of information including CPU, memory, network, and detailed hard disk drive usages. Using this software, you may discover what is limiting your system performance in each occasion.

Available as installer or portable, and pretty lightweight too - it's using only 7 MB RAM."

"There is TinyResMeter:

TinyResMeter takes less than 3MB Private Bytes and about 40MB of VM (typically). It is quite configurable too.

Notes from the site:

A small tool that displays useful information about system resources
in real time, but it also gives much more detail when you
right-click on the displayed fields


It is written 90% at pure API level to keep it as small as possible.
It does not require any extra non standard DLL.
It does not modify/write inside the Registry (except if you set it
to autorun).
It uses less memory and resources than most tools of its kind.
It uses a very simple but efficient small display interface.
It does not use any installer that could increase EXE size; once
downloaded you can use it immediately.
It can be simply copied and executed on any machine with no need for
an installation procedure.
It use very small screen space.
It's perfect tool for low-end computer or NetBooks"

CPUMon is also a tiny application that can sit in the corner of your screen or in the system tray.
