Add UMA for tracking decode times for out of raster and raster tasks. |
||||
Issue descriptionWith checker-imaging, we expect to see a decline in image decode tasks that block raster. Currently the metrics that track the length of image decodes are Renderer4.ImageDecodeTaskDurationUs.Software/Gpu. We should update them to separately track decodes for out of raster tasks and bucket the clients of these tasks (decode API versus checker-imaging) separately.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/97474434c7f06805f9bdc97c2848ef25cf07f550 commit 97474434c7f06805f9bdc97c2848ef25cf07f550 Author: khushalsagar <khushalsagar@chromium.org> Date: Fri Jun 02 02:35:33 2017 cc: Add UMA for tracking decode duration for out of raster decodes. We currently bucket UMA for all decode tasks in a single histogram. With checker-imaging enabled, we expect to see a decline in the decode duration for images decoded with raster. Add UMA to track these seperately.
