I think this question was asked by someone else as part of another thread back in January, but I couldn't find an answer on the list archive. What do the zeros for "entries" mean in a time profiling report? If I want to know why "getAppropriatePreds" takes up so much time (14.7%) in my code, does the zero mean an overflowed count or that the cost centre has never been entered? I'm using 5.04.2 on Linux, and my program is compiled with -O -prof -auto-all.

I think the best answer to give here is that the entries count is not at all reliable. Please feel free to file a bug, we'll get around to it next time I have the profiling system paged in ;-) Cheers, SImon
