Subject: ocamlopt performance in 3.11
Pleased to say that I've got my 3 current projects compiled and running
under 3.11+beta1

Unfortunately for one of the projects, its "reference" run (a
computationally intensive, repeatable operation the speed of which interests
me) has gone from repeatedly taking ~38 seconds in 3.10.2 to ~46 seconds in
3.11.0+beta1. The other two projects don't have as easy a way for me to
calibrate speed (they spend most of their time blocked on I/O anyway!).

Has anything apart from the linker changed much in the 3.11 code generator
and has anyone else noticed a performance drop in any other programs?
