Wow, this is really encouraging. I can see various reasons why the build is
now faster. Some optimisations were accidentally deactivated in the past,
and slot accessors is now way way faster thanks to specific dispatch code.
Does Axiom use a lot of structures and CLOS objects? If so, it can also
profit from a more relaxed safety level which is similar to that of SBCL's
and which also prevented certain inline code...
It was always on my todo list to have a look at the OpenAxiom builds again,
but job gets in the way so often!
Now, if only debugging with ECL could be just as pleasant

Yeah, *I* would also love that :-)
