However, to visually stand out it probably would be good to have the call arcs drawn with different widths (that has to wait for the Qt4 port...). Wouldn't it be enough to have a difference column in the function list on the left? > in the task).

A question for the Valgrind developers: I have made changes to Valgrind's core in order to get the drd tool working. How should I proceed to get these changes applied to the official Valgrind distribution ? Should I split up the patch ? Should I wait until after release 3.x.y ? |

What he was suggesting was a simple difference - literally subtracting one set of results from another one (having carefully lined up various call trees etc. as required and where possible) It's main use would be to make any performance impacts / regressions from one software version to another _really_ stand out. They have tried two sessions side by side but the increase distributed across a set of functions was too small to stand out of the overall picture, although the impact of the actual difference in itself is quite measurable. It might be better to get Andy to join the list so he can explain it properly (he is in a different team to me so I'm not directly involved in the task). On the other hand, I know that we both feel cheeky for asking as neither of us could help to implement it.
