What does CPU Usage History Box In Task Mgmt shows?

Hi EEs,

I have one IBM Server in which 2 processors are running & 25 xp client computers with PIV processes.

* In Server's Task Mgmt i can see 4 boxes for CPU usage history & in other PCs i can see 2 box for CPU Usage history under performance tab...why?

* What is PF Usage in performance tab?
* What does Physical Memory (Total, Available & System Cache) represents?
* What is Kernel Memory show like Total, Paged & Nonpaged?
* What is the means of those figure's shown under I/O read & I/O write in Processes tab or task manager?

For your refe. i am here with attaching the snap of my query as well.

I Appolonia if I asked too many questions in under one, but its all are co-related to Task Manager over-all.

an earlier reply will be highly appreciated,

many thanks,

My question was-------how many boxes i will see under CPU Usage History if I have two CPUs (Xeon) in Performance & how much for one CPU (PIV)

In Kernel total is representing the total available memory or the total used memory? Ps explain.

awaiting for your earlier reply,

many thanks.

Now here some terms i request you to make me understand in dept:-

* Hyperthreaded & non Hyperthreaded CPU
* Single Dual-core non hyperthreaded
* hex-core hyperthreaded

Does kernel memory is same which we set in Virtual Memory under Performance Option in system property's advanced button?

One more thing :- If i have one GB physically installed in XP sp3 what figure i need to set for Virtual Memory.....like currently i have set as below:-

Total physical memory = 1 GB
Custom Size :
Initial Size (MB) : 1536
Maximum Size(MB) : 3072

Kindly advice the right figure & explain my queries asked above.

many thanks in advice,

Kindly advice if i have 2 GB RAM then what racio i have to put if i also want to equal as a min & max setting for virtual memo?
Pls explain why we keep this equal?
thanks,

The general rule-of-thumb is to use a maximum of 1.5x the actual memory ... so if you have 2GB RAM you should set the maximum size to 3GB. The reason many folks like to set the min and max the same is so the page file will always be the same size -- there won't be any shrinking/growing of the file, so it won't become fragmented over time.

Kidly advice What is the best to set....whether Programs or Background Services under Processor Scheduling & Programs or System Cache under Memory Usage in the Advanced Tab if I am using XP SP3 & Windows Server 2k3.

awaiting for your earlier reply....
