I second this.  On my machine, the bytecode is 3 times slower than the
native code, and it makes a usability difference : 2s vs 6s startup
time on my P4 at 2.4GHz ; ara parses 39658 packages...  On a Pentium
120 this would give approx.  20s vs a full minute and many people still
have these, and ara will be important for these people since they usually
can't use GTK2 stuff like Xara or Synaptic because it's too heavy.

Another advantage of native code is that it doesn't depend on Ocaml

PS. Thomas, Sven, George : are you all subscribed to debian-ocaml-maint ?
