Great, you seem to be getting some excellent results.
I have also wondered whether the .ucm files are needed after these
have been built; if not, we should consider supplying with perl only
the optimised table data if that could give us a space saving in the
distribution - it would cut build time significantly as well as
allowing us to consider algorithms that take much longer over the
table optimisation, since they need be run only once when we
integrate updated .ucm files.
The main reason the "compile" was left in was that the tables are different
for UTF-EBCDIC machines. Otherwise just shipping the .C files used
to generate the .so-s is a good idea - I was also struggling to come up
with a "data" format that would be as efficent in space/time as the code
version.
If we eliminate .ucm-s from distribution then I think it would be
useful to have something which will print them out from the internal
form.
