Windows Performance Tab Question

I know that XP is a bit different than '98 but when I bring up the task manager and go to the "performance" tab I really don't understand what everything means. Physical Memory, Kernal Memory, Comitt, Page File.... can someone give me a little lesson in how to interpret my performance?

My system has 128mb RAM. That said, here is what my performance reads now:

Physical.........129580k
available..........64204k
system cache...72216k

kernal...............31756k
paged...............27252k
nonpaged...........4505k

Page File usage: 126mb

total: handles, 5282
threads, 298
processes, 25

Commit Charge:
total............129584K
limit.............380536k
peak............185404k

Is this good? How do I use this info to determine how well my computer is performing? Why is Physical and Commit slightly different?

 

For a detailed description of what they are, open up the task manager and click on help, under the contents go to performance fields overview. They have pretty good explanations of what they are.


Without knowing what you use the computer for, I would say those are pretty good for things like surfing, light gaming, email and such.
