Hi, I became curious about this myself and ran a simple benchmark for automatically generated binding code of increasing size.
The compilation times for Boost.Python and pybind11 turn out to be fairly similar. However, there is a significant difference in terms of the size of the compilation result, which is almost twice as large for Boost.Python. See the details here: http://pybind11.readthedocs.org/en/latest/benchmark.html <http://pybind11.readthedocs.org/en/latest/benchmark.html> Best, Wenzel > On Oct 19, 2015, at 9:58 PM, Francesco Biscani <bluesca...@gmail.com> wrote: > > This looks really neat! > > Do you have any measure on the memory/cpu performance wrt Boost.Python when > compiling large bindings?
