Hi Ross,

I didn't test the overhead.

The reference manual says that this variable is only useful when users 
want to generate a source mirror.

Some related info from bitbake/Changelog
"""
         - Add BB_GENERATE_MIRROR_TARBALLS option, set to 0 to make git 
fetches
           faster at the expense of not creating mirror tarballs.
"""

Besides, testsdkext is a task to verify correctness. It does not affect 
the generated eSDK that the users actually use. I'm not sure if I should 
change some default value merely to speed it up. I'd rather do some 
tweaks to this task instead of doing some change which could affect the 
building results.

That's why I chose not to change its default value.

I've removed the 'protocol=file' and sent out V2.

Best Regards,
Chen Qi
