NAME

SYNOPSIS

DESCRIPTION

Run any vips program with the --vips-profile option to generate a file called "vips-profile.txt". This contains timing information about CPU use, memory use and thread synchronisation.

Run vipsprofile(1) to load this file, calculate some statistics, and draw a graph of evaluation saved to vips-profile.svg. This analysis can help track down performance problems.

For example:

$ vips sharpen shark.jpg x.jpg --vips-profile recording profile in vips-profile.txt $ vipsprofile reading from vips-profile.txt loaded 3622 events total time = 0.138322 name alive wait% work% unkn% memory peakm worker 20 0.069 34.5 58.9 6.65 3.14 5.56 worker 21 0.07 1.36 60.2 38.4 2.65 5.07 worker 22 0.07 33 55.8 11.1 2.62 5.04 worker 23 0.072 34.2 59.7 6.15 2.72 5.14 wbuffer 24 0.075 99 1.03 0.00401 0 0 wbuffer 25 0.075 95.6 4.39 0.00667 0 0 main 26 0.14 52.8 0 47.2 -11.1 0.787 peak memory = 21.6 MB writing to vips-profile.svg
