Wesley, Yakun:

I hope you guys are doing OK with the restrictions and stay healthy!

I did a review of the numbers that Yakun provide in a prior email 
(summary here)

Package Compile
timeconsumption				with pbr	without pbr
the first time				0.287s		0.301s
the second time				0.322s		0.351s
the third time				0.554s		0.235s
the fourth time( deb package)		0.299s		0.292s


Can you please provide more details about what your actual test 
methodology (and/or scripts) was?

I think at some-point it was suggested that 2 packages (python and 
non-python) should be used. They should then be compiled / cleaned in a 
loop of about 10-12 times to ensure any caches are cleared. Then an 
average and deviation be determined.

Thanks
    Sau!
