Skia Perf
|
|
=========
|
|
|
|
[Skia Perf](https://perf.skia.org) 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://perf.skia.org/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://perf.skia.org/#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://perf.skia.org/#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://perf.skia.org/#1878).
|
|
|
|
count(filter(""))
|
|
|
|
See Skia Perf for the [full list of functions available](https://perf.skia.org/help).
|
|
|
|
Embedding
|
|
---------
|
|
|
|
Once you create a shortcut, which may or may not include calculations, you
|
|
will be presented with the code to embed that graph as an iframe. For example,
|
|
here is an embedding code for showing the ratio of all 565 tests over all 8888
|
|
tests:
|
|
|
|
<iframe src='https://perf.skia.org/frame/#4518' width=500 height=300 frameborder=0></iframe>
|
|
|
|
And the embedded graph appears as:
|
|
|
|
<iframe src='https://perf.skia.org/frame/#4518' width=500 height=300 frameborder=0></iframe>
