Hi,

We have developed our private OS and we want to benchmark the performance
of it, including time of context switch, interrupt latency, IO output and
so on ...

We want to study from Linux firstly, so could you guys give me some guide
of Linux benchmark testing, including test methodologies, test code and so
on.

Thanks in advance.

I am not sure if this one is directly relevant to your case, but you might
want to take a look at LTP: http://ltp.sourceforge.net/

                     ^^^^^^^^^^^^^^^
            To what degree does "private" goes? Is your private OS an newly created one from scratch or based on one of open source version?

Hi,

Benchmarking is a difficult ask. You need to define the matrix of what all
things you would be measure and for what kind of workload. This data should
be directly influenced by the application of the OS, where and how your OS
would be used, what are critical performance areas you need to focus on.

First of all whats the type of kernel you guys have implemented. The main
thing is, what were the design decisions taken while implementing the
policies, how should they perform in theory. After listing all these things
down, you need to design benchmarking software modules for that though you
can have a look at some existing once for the other OSes.

For linux,

1. systemtap.
2. perf.
3. Vtunes from intel.
4. ftrace.

Also, you would be required to emulate the workload to the real load that
would be on your OS and do benchmarking.
