Check this out ignore punctuation using manipulator. Basically you can get the stream to treat the comma like it was a space by imbuing it with a custom std::codecvt. That way you don't need to run over the line and remove commas from potentially arbitrary long lines.

Otherwise memory reallocations are going to be one of the main slowdowns of your program. If you do not know the number of lines beforehand you should be able to estimate them from the size of the file. | |

This is the best fit problem for std::ctype<char> (note that it is very different from its template version). Just set the comma to be space.
