Have the same problem as Dirk, got just 1 call to NTDLL.dll while sampling.

I’m on Windows 7 64 bit – 2 CPU quad core.

Regards,
Hector

We found out a lot of bottlenecks in our applications. Best is that there is no need to change source code like in instrumenting profilers. Unfortunatly Sampling profiler is not working correct in Win7. Exe compiled with TD32 debug info can successfuly profiled in XP but same exe not in Win7. It shows random classes or just a 100% call in NTDll.dll One thing i saw is writing an error.log file in C:\ (this is not allowed due to permissions). It would be great if SamplingProfiler is working in Win7 Thanks and best regards Dirk Carstensen Hi Eric,

I can't tell, from the description of SamplingProfiler, what it actually samples. I hope it samples the call stack, and I hope it samples it on wall-clock time, not throwing away samples that occur during I/O that the thread has requested. I'm sure you understand that the fractional cost of any line of code is nicely estimated by the fraction of samples it appears on, and that recursion is a non-issue.

Other modes are okay. (This is Delphi 2010, Windows 7.) Eric, FYI, the profiler doesn’t seem to work under “Start Sampling Immediately” mode. Other modes are okay. (This is Delphi 2010, Windows 7.)
