An article Don’t Compare Averages from Martin Fowler has lots of good info about data visualisation techniques.
Wanted to know a little more about the pros and cons of different compression tools and strategies.
Found this article A Quick Benchmark: Gzip vs. Bzip2 vs. LZMA and looking at that gzip is a pretty clear winner I think wrt my concerns (i.e. fast compression over high compression). Also found gzip vs. bzip2 which concluded basically the same.
