30 - 60 x, but is very workload dependent, much more so than memcheck > Does it depend on the number of threads/locks? It depends on a lot of things. The following are very expensive: - deleting (eg, free, delete[], stack deallocation) containing a lock - pthread_join > Do you have any suggestions on further analysis/improvements of helgrind > performance? Run (the problem program) with -v. It prints ~ 100 lines of stats at the end. Send those.
