In other news: I just pushed a bunch of patches to heaptrack git which allow you to do time-diffing. I.e. you can now select a time range in the charts and then request filtering to show the delta costs between the two time points. This should allow you to solve your problem nicely. Alternatively, you can also runtime-attach heaptrack after you finished your initialization phase to only record the main computational loop. The overhead should be minimal or actually close to zero when your main loop isn't allocating anything. Cheers -- Milian Wolff m...@milianw.de http://milianw.de
