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

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