Hi Folks,

I just started performance profiling my app for the first time with 5.1. I have been using memory profiler extensively. This might be newbe type stuff, but I'm encountering what seem to be a lot of random bugs. For example:

1. the ants hangs when changing the time bar
2. I got a blue screen of death at one point
3. some method times report negitive miliseconds (some in the thousands)
4. In the code view not all lines of code have metrics (might be a compile issue on my side?)
5. after I save results ants still warns me that results are not saved before exiting
6. etc.

I have noticed some out of memory exceptions being logged to the perf profiler log folder

So I was wondering if you all had any patch releases ready or if you had any coming.


Here's a example of one of the performance profiler logs:

Hi there - sounds like you are having a lot of known issues at once.

The negative times are a conseqeunce of very modern instruction pipelining and the effect it has on the algorithm we use to compensate for it. You can get more "real-world" times by de-selecting "Adjust timings to compensate for overhead added by the profiler". I recommend using the "fastest, most accurate" mode of profiling at the same time.

>>>4. In the code view not all lines of code have metrics (might be a compile issue on my side?)

Ensure that the pdb files from the debug build are synchronized with your source cdoe. If some lines are still not getting any timings- this is probably because they are not being run (at least as far as the "selected dataset" goes).

>>>5. after I save results ants still warns me that results are not saved before exiting

Is this reproducible - if so, can you write out the exact wording of the error message pelase (I'll check the source using that literal).

We haven't had a BSOD for over a year so, can I ask, have you had any hardware changes recently as, as far as trouble-shooting goes, that would be my first line of enquiry.
