Skia Perf
|

|
|
=========
|
||
|
|
|
||
|
|
[Skia Perf](https://skiaperf.com) is a web based interface for exploring
|
||
|
|
performance data produced by `nanobench` and the code size bot. The data
|
||
|
|
includes:
|
||
|
|
|
||
|
|
* The nanobench test times in ms.
|
||
|
|
* Total memory consumed during a nanobench run.
|
||
|
|
* Code size for various symbol types in bytes.
|
||
|
|
|
||
|
|
All of the data can be plotted and also can be [analyzed using k-means
|
||
|
|
clustering](https://skiaperf.com/clusters/).

Calculations
|
||
|
|
------------
|
||
|
|
|
||
|
|
Skia Perf has the ability to perform calculations over the test data
|
||
|
|
allowing you to build up interesting queries.
|
||
|
|
|
||
|
|
For example, this query displays the [total code size of the library over time](https://skiaperf.com/#1877):
|
||
|
|
|
||
|
|
sum(fill(filter("config=memory&sub_result=bytes")))
|
||
|
|
|
||
|
|
This query displays [the ratio of playback time in ms to the number of ops for desk\_wowwiki.skp](https://skiaperf.com/#1876):
|
||
|
|
|
||
|
|
ratio(
|
||
|
|
ave(fill(filter("name=desk_wowwiki.skp&sub_result=min_ms"))),
|
||
|
|
ave(fill(filter("name=desk_wowwiki.skp&sub_result=ops")))
|
||
|
|
)
|
||
|
|
|
||
|
|
You can also use the data to answer questions like [how many tests were run per commit](https://skiaperf.com/#1878).
|
||
|
|
|
||
|
|
count(filter(""))
|
||
|
|
|

|
