| ==12190== | |
| ==12190== Some hints: (see --help for command line option details): | |
| ==12190== | |
| ==12190== * summary stats for whole program are at the top of this output | |
| ==12190== | |
| ==12190== * --show-top-n= controls how many alloc points are shown. | |
| ==12190== You probably want to set it much higher than | |
| ==12190== the default value (10) | |
| ==12190== | |
| ==12190== * --sort-by= specifies the sort key for output. | |
| ==12190== See --help for details. | |
| ==12190== | |
| ==12190== * Each allocation stack, by default 12 frames, counts as | |
| ==12190== a separate alloc point. This causes the data to be spread out | |
| ==12190== over far too many alloc points. I strongly suggest using | |
| ==12190== --num-callers=4 or some such, to reduce the spreading. | |
