* perf: Refactor some common macros to cairo-perf.hBryce Harrington2014-04-181-2/+0
| | | | | | | | These macros are standard in src's cairoint.h and test's cairo-test.h internal header files, so for consistency do the same thing with perf's cairo-perf.h. Reviewed-by: Uli Schlachter <psychon@znc.in>

* whitespace: Fixup formal arguments and tabs in boilerplate/ and perf/.M Joonas Pihlaja2010-06-241-12/+26

* [perf] Trim outliers from chartChris Wilson2009-08-301-39/+172
| | | | | | | Use "mild outliers" method to remove exceptional speed-ups and slow-downs from the graph, so that the majority of information is not lost by the scaling. Add the timing labels to the bars so that the true factor is always presented.
* [perf] Add charting utilityChris Wilson2009-08-291-0/+751
cairo-perf-chart takes multiple runs (currently it is limited to prefiltered data sets) and pretty-prints a chart showing performace improvements/regressions (in either ASCII or HTML) along with a cairo-perf-chart.png
