[INFO] Speeding up the default browser rendering by a huge amount..
Sorry if this has been posted before, but this worked for me pretty well... just type
In the address bar. Now go to "Settings" in the tool menu, go to the Debug option, and DISABLE "Use Wide Viewport".
This gave me a huge rendering-speed increase (while slightly lowering font size). The only option I have enabled is "OpenGL rendering".
You might have to restart the browser for it to work; enabling and disabling OpenGL resets the engine and seems to work too.
You're supposed to DISABLE it if it's enabled by default on your custom ROM.
Sometimes the settings turn off automatically, probably a browser restart. I left mine in sleep overnight, and when I woke it up, pages were rendering slowly again. Enabling about
:debug again fixed it.
