Hey, that's awesome. I've already noticed that gcc 4.4.5 was much faster (~2x) than MSVC 2008, and this is why I'm distributing win64 binaries compiled with MINGW/GCC 4.4.5. The results on the Mac platform also confirms that latest versions of GCC can optimize Blosc really well (I've seen in your logs speed-ups up to 2.5x with gcc 4.5 compared with 4.0 in some important cases). Did not know about Clang compiler, but it looks like a very interesting project. Thanks for sharing this! PS: I'm CC'ing to pytables-users list as this can be interesting for more people indeed! -- Francesc Alted ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
