Re: RICHIO performance - 3 to 30 times slower than std::ifstream

 

Really good to know. Maybe these results should be noted down somewhere (code or guidelines?) so this information is not lost over time.

What about wxFFileInputStream instead of wxFileInputStream?

wxFFileInputStream appears to be about 5-6 times faster than
wxFileInputStream, but that's still much much slower than RICHIO or
std::ifstream.
