MLton runs fine on FreeBSD.

## Notes

- MLton is available as a FreeBSD port.

## Known issues

- Executables often run more slowly than on a comparable Linux machine. We conjecture that part of this is due to costs due to heap resizing and kernel zeroing of pages. Any help in solving the problem would be appreciated.

- FreeBSD defaults to a datasize limit of 512M, even if you have more than that amount of memory in the computer. Hence, your MLton process will be limited in the amount of memory it has. To fix this problem, turn up the datasize and the default datasize available to a process: Edit /boot/loader.conf to set the limits. For example, the setting

         kern.maxdsiz="671088640"
         kern.dfldsiz="671088640"
         kern.maxssiz="134217728"

  will give a process 640M of datasize memory, default to 640M available and set 128M of stack size memory.
