I've investigated A2DC in both Android and Tizen. A2DC is already enabled in Android.
When it comes to Tizen, performace is improved by 2~3 times!!! Now, Android and Tizen has almost same performance. I'll apply it to Crosswalk soon. (https://github.com/crosswalk-project/crosswalk/pull/1207) In technical detail, Current Tizen Crosswalk uses threaded compositing + software canvas. I measure four combinations. The result perfomance: threaded compositing + A2DC > A2DC >>>>> sw > threaded compositing + sw 1. http://www.craftymind.com/factory/guimark3/vector/GM3_JS_Vector.html sw: 17.99 threaded comp + sw: 14.91 A2DC : 37.52 threaded comp + A2DC: 44.82 2. http://www.craftymind.com/factory/guimark3/bitmap/GM3_JS_Bitmap.html sw: 20.51 threaded comp + sw: 17.16 A2DC : 49.98 threaded comp + A2DC: 54.58 3. http://www.craftymind.com/factory/guimark3/compute/GM3_JS_Compute.html sw: 20.98 threded comp + sw: 19.36 A2DC : 35.47 threaded comp + A2DC: 39.18 Let's analysis the result, sw is faster than threaded compositing + sw, because threaded compositing + sw needs to copy bitmap one more time. A2DC is pretty faster than software canvas, because of GPU. threaded comp + A2DC is faster than A2DC, because 1) both need to copy bitmap the same time. 2) replaying in compositor thread reduces Blink thread workload. more detail: https://crosswalk-project.org/jira/browse/XWALK-73 - DS --------------------------------------------------------------------- Intel Finland Oy Registered Address: PL 281, 00181 Helsinki Business Identity Code: 0357606 - 4 Domiciled in Helsinki This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
