Does the kernel time in the profiler only indicate the kernel execution time of ONE execution? I'm assuming so since if I change iterations to 5000 or something like that, nothing in the profiler changes, is this correct?
Also, the execution time varys greatly, why would that be? For example, in if I keep running Sorbel Filter, I get kernel executions times from .332xxx to 1.40xxx.
That's a pretty big swing, any reason this might be the case?
Also, why doesn't the profiler show every kernel and it's execution time? Does it onlly show the last kernel execution?
