Hi,
I have a small busybox applet called "whatisup". It's a kind of high level
"procfs" based profiler (/proc/interrupts /proc/stat and /proc/cpuinfo);
it's
something between "time" and "top", plus counting interrupts and context
switches.
It can be run with and without arguments.
If you run it without arguments (type only the command name) - it waits
until Ctrl/C and
uses its own lifetime for benchmarking.
If argument added after the command name (argument will be a command to
run),
in that case it uses the command?s lifetime for benchmarking.
Please have a look at the samples and give me your opinion
if this is what can be useful for the project?
Patch to the trunk/busybox attached.
Cheers,
Vlad.
