New testbed based on minilzo complete.
Results from run using 1000 runs to generate averages:
1000 run averages:
'Tiny LZO':
        Combined: 55.196 usec
        Compression: 37.132 usec
        Decompression: 18.064 usec
'miniLZO':
        Combined: 55.785 usec
        Compression: 40.862 usec
        Decompression: 14.923 usec


Great!

I believe its now ready for mainline. We can do further cleanups and
optimizations there - more users of this code will surely drive more
enhancements.

(using (tiny/full)/100 for percentages:
'Tiny' is 0.9% faster on average


I think this is more appropriate: [(full-tiny)/full]*100
=> tiny is ~1% faster on average.


Same for the Compression
'safe' decompressor from tiny is 1.2% slower than unsafe from minilzo)


This is expected :)

Nitin
