The main problems I've had with valgrind are speedYes, that is known.and false positives.That one is new to me. Can you elaborate?IIRC the problem was using a different library, and tracing which problems are yours and which are of the library. See for instance this rant http://www.mega-nerd.com/erikd/Blog/CodeHacking/house_of_cards.html I haven't really got into this, so maybe the suprresion files does allow you to quickly fix it.
suppressions are very easy to generate (after you learn to spell the word ;) - you run valgrind with the flag "--gen-suppressions" - and every time it hits a problem - it will ask you whether to generage a suppression. if you say yes, it'll print the suppression info on screen.
you copy this to a file, edit it a little to your liking (to make it a bit more general - i.e. not depend on the specific part in your code that invoked the problematic 3rd-part library), and it works.
by the way - we had real false-positives in valgrind, that were fixed in a later valgrind version. so you will have to check this as well.
