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. compose InfrequentCheck 1137 12280580 2.1 2.5 2.1 2.5 align InfrequentCheck 1127 0 3.7 6.2 8.3 6.7 align2 InfrequentCheck 1139 8577943 0.4 0.0 0.4 0.0 lookupModeArgs InfrequentCheck 1136 86747940 4.2 0.4 4.2 0.4 getAppropriatePreds InfrequentCheck 1126 0 14.7 6.6 14.7 6.6 Amanda
