Owen O'Malley commented on HADOOP-4874:
---------------------------------------
Based on the benchmarks done by the QuickLz guys at http://www.quicklz.com/, it
looks like fastlz, which has a usable mit license, or liblzf, which has a bsd
license, may be the best replacement for lzo. (Quicklz claims to be faster than
either, but it is gpl too.)
Times to compress and decompress 1gb using the quicklz benchmark numbers:
quicklz (gpl): 3.8 + 3.5 = 7.3 secs; 47.9%
lzf (bsd): 5.8 + 2.9 = 8.7 secs; 51.9%
fastlz (mit): 6.3 + 2.6 = 8.9 secs; 50.7%
lzo (gpl): 6.6 + 2.5 = 9.1 secs; 48.3%
zlib: 23.2 + 6.6 = 29.8 secs; 37.6%
> Remove bindings to lzo
