SYNOPSIS

9       vipsprofile
10

DESCRIPTION

12       vipsprofile(1)  analyzes the file written by the --vips-profile option,
13       calculates some statistics, and draws a graph of evaluation.
14
15       Run any vips program with the --vips-profile option to generate a  file
16       called  "vips-profile.txt".  This contains timing information about CPU
17       use, memory use and thread synchronisation.
18
19       Run vipsprofile(1) to load this file, calculate  some  statistics,  and
20       draw a graph of evaluation saved to vips-profile.svg. This analysis can
21       help track down performance problems.

26         recording profile in vips-profile.txt
27         $ vipsprofile
