Hi All,
I'm trying to analyze the performance of Linux Kernel.
I need to compare this with VxWorks performance.
What are the performance benchmarks do we have to take?.
How can we test the efficiency of the features provided by the OSes like
Scheduling, Mem. Management, VM, network buffers (this
Check the Wind River site, I'm sure they will have all these things in
some sales brochure.
It really depends on what real-time aspects of the OS you are after.
Things like context switching, file system support, interrupt
latency

with some traffic generator tool).
I don't know about VxWorks but for the linux kernel take a look at ftrace.

Dear all,
If a kernel code requires an external loadable module then will it get
loaded automatically? If the code requires the kernel module much earlier
than the filesystem is loaded and the module is made available than I should
provide it earlier. This should require to make the external
Thanks Joel, but m not sure on how i can use ftrace. as both OSes may
have different calls to compare...
Bruce, yes, even i have to handle those things..i mentioned to just
name a few..How can we test context switching and interrupt latency?.
Are there any tools for this?.
I just saw netperf to

hey,
use kernel Auto test suite for all the kernel feature testing.
Best of luck

Hi, Nameless!
A real name motivates probably more people to answer BTW.

Yes it will be, after you install a module, depmod is run which
generates a file called modules.dep . modules.dep lists all
dependencies for every module. These dependencies are then
automatically
