winwire looks pretty fast to me. 2.5 alpha, XP, Pentium 4 1.8 GHz.
Judith's IDE is a special case.
It has code at the very beginning of the source
to display a splash screen. Under 2.4 this splash
screen appears almost immediately, then you wait for parsing
to complete. That's because 2.4 will execute code before it
has finished parsing the program. 2.5 parses the *whole* program before
executing anything. Including Win32Lib etc., the IDE is
100,000 lines of Euphoria code. That's a lot
of parsing to do, and 2.5 has a Euphoria-coded parser.
2.4 has a C-coded parser. So you might consider
the IDE to be the "worst-case" example. It's the biggest
Euphoria program I know of.
If you bind the IDE using 2.5, or translate/compile it,
it will start up much faster, because no parsing need be done.
(Bound programs under 2.4 must be parsed).
Other very large (tens of thousands of lines) programs may also
appear to start up a tad slower using the 2.5 interpreter,
but we're only talking about a second or two (unless you have an ancient
machine). I think with the vast majority of programs,
you'd hardly notice any difference. As computers get faster,
this small difference will get even smaller.
