<!-- This benchmark aims to accurately measure the time it takes for CanvasKit to render
|
|
an SKP from our test corpus. It is very careful to measure the time between frames. This form
|
|
of measurement makes sure we are capturing the GPU draw time. CanvasKit.flush() returns after
|
|
it has sent all the instructions to the GPU, but we don't know the GPU is done until the next
|
|
frame is requested. Thus, we need to keep track of the time between frames in order to
|
|
accurately calculate draw time. Keeping track of the drawPicture and drawPicture+flush is still
|
|
useful for telling us how much time we are spending in WASM land and if our drawing is CPU
|
|
bound or GPU bound. If total_frame_ms is close to with_flush_ms, we are CPU bound; if
|
|
total_frame_ms >> with_flush_ms, we are GPU bound.
