Thank you!  In the meantime, I happened to produce something similar.  
Unfortunately even mine was too late for another round of tests to present it 
in our git vs. svn comparison (with todays deadline) - so we just mentioned 
in the report that the tested repository still had reserves [but the numbers 
were quite nice even with the 2.5G one ;-)].

The 'minimal3' case was with '--window=250 --depth=250', 'minimal4' was 
with '--window=250 --depth=50'

I tried the --depth=50 because I read 'making it too deep affects the 
performance on the unpacker side' in the man page.  How big the difference 
could be in practice, please?

Regards,
Jan
