sending data to remote compilor part.
it takes around 40 second and my timeout setting was 30 second. I increased it to 60 second now works. I think my upload speed is slow so it takes some time with 3mb of files.
When you compile in debug mode it doesn't send the asset files to the builder. The files are sent (when needed) from the PC to the device directly.
In release mode it sends everything to the builder. I plan to make it "smarter" in the future to make this process lighter and allow the builder to reuse existing files if they haven't changed.
