That is a *lot* more reasonable, although Spirit is still most definitely faster then the built-in functions. :)
That's good though - one up for Boost!
My latest benchmarks for integers and floating points reveal a 3x speed over atoi/strtol and friend C functions. You mentioned a need to parse small numbers very quickly? Spirit does. The tests I have take that into consideration too. If you guys want to take a peek, it's in the Boost trunk in libs/benchmarks. Some numbers: /////////////////////////////////////////////////////////////////////////// atoi_test: 0.9265067422 [s] {checksum: d5b76d60} strtol_test: 1.0766213977 [s] {checksum: d5b76d60} spirit_int_test: 0.3097019879 [s] {checksum: d5b76d60} /////////////////////////////////////////////////////////////////////////// atof_test: 7.3012049917 [s] {checksum: 3b7d82b0} strtod_test: 8.0042894122 [s] {checksum: 3b7d82b0} spirit_double_test: 2.6729373333 [s] {checksum: 3b7d82b0} This time, I am using the benchmarking harness by David Abrahams, Matthias Troyer, Michael Gauckler. It's the one used in timing the overhead of Boost.Parameter. You are welcome to try it out with your timer, Edward. Regards, -- Joel de Guzman http://www.boostpro.com http://spirit.sf.net
