It can be, but it's certainly not perfect.
But for the pure speed, i must refer this inferior compiler technology to
the outdated desk.
This seriously makes me wonder which compilers you have been using.
A complex program will be a factor 3 slower with it at least.
Let's assume[1] that java is 3 times slower than c/c++ at run time, but
3 times faster at getting an idea form pure idea to running code that
can be evaluated.
I'll take java any day.
When I finally run out of ideas to code, maybe I'll port to c++, or
maybe i'll run it through gcj (http://gcc.gnu.org/java/) which now
supports the full java 1.1 and happily builds native binaries for any
platforms supported by gcc. Or maybe, by then the java compilers will be
as mature as the c/c++ compilers are today and the speed difference
won't be significant.
In fact small 30 line programs already are to my amazement not seldom up to
a factor 3 slower.
Certainly, and most of that is JVM initialisation, a one-off hit.
Running in Ant or similar makes things orders of magnitude quicker (you
get the overhead of initialising a new thread within the current JVM not
that of initialising new process and initialising a new JVM).
