I think it's amusing (in a sad sort of way) that the immediate reaction is that
"it's slow because of Todd's code, which needs improvement" instead of "it's
slow because of Java". Other major projects which have been implemented in Java
(Corel's Office Suite for example) also had performance problems sufficient to
basically scuttle those, too... and those presumably had nothing related to Icon
in them. :-)
> (2) Todd may have reached a fundamental performance limit that cannot be
improved upon in this context, except by moving to compiled C++. That
may explain why Todd is presently working on a Java-->C converter. If
so, it argues again for an Icon-->C++ converter and against an
Icon-->Java converter.
Honestly, I don't see a whole lot of reason for going to **either**. Icon
(IMHO) works just FINE as it is. Any reason for going Icon->Java, in whatever
case, has nothing to do with any anticipated PERFORMANCE improvement!
