Hi, I just want to know why the impact on der time of the profiled application is so great, when running time profiling in normal mode. Under the new sample mode there is nearly no impact on the time. But when using the normal mode the profiled app is 10-15 times slower even when I do no recording. During recording this impact would be fine but when I do no recording I expected a much lower imapct on the profiled application. best regards Klaus Neuberger
