Right -- that part was not an answer, but an indication that looking around for explanations on how to read any profiler's output would help. Later on I tried to explain some of his output, and of course, having someone else improve the documentation will be helpful. > I will say I was equally stumped when I used the profiler, and i > thank Robby for explaining bits and pieces to me. > > In general, the entire answer suggests that there is serious room > for improvement.

Presenting the information in a useful way *is* the main problem here. Doing that via a plain text file is making it particularly challenging. > When I see such things, I sure wish we had an "HCI department" :-) That would help, obviously, since I don't have good ideas on how to improve the textual output. That's why I said that a good direction is to produce some output that existing profiler visualization tools can use -- my guess is that there are projects that did considerable work on that already. A quick search got me here: http://stackoverflow.com/questions/54971/profiling-visualization-tools which has a number of pointers that look useful. It also looks like graphviz is the most popular recommendation, so perhaps that's the best way to go -- slapping a GUI or an HTML rendering around it. (And in case it wasn't too clear -- if anyone is interested in taking this, I'll be very happy to help from the profiler's side.) -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://barzilay.org/ Maze is Life! _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
