Hi List,

 

I wrote an OCaml function to read a text file with a million of lines with  five separate columns for spaces. I based myself on previous messages of Caml-list, but however the work is taking time frightful (many minutes).

This function written in C, for example, does not take more than 4 seconds.

 

I am executing the program in a PC Pentium III of 128 MB of RAM under Windows platform. How would be implemented the function to decide this problem?

File format:
<vertex #> <x> <y> [attributes] [boundary marker]

Thanks,

André
