I'm just confused as to what people mean when they say java is slow,
or is this just a myth?
It's a myth. Your application performance has very little to do with
what language you happen to be using. And as far as 'raw performance'
(e.g. how long does it take to loop through five millions objects),
they are useless as they have nothing to do with real applications.
It is slow, despite the fact that the JIT does OK on some
non-realistic micro-benchmarks (and even there C was faster once
optimization was turned on). It also requires huge amounts of memory,
which not only slows the java process itself down, but imposes a heavy
penalty on the entire system.
Sure... and my assembler is faster and slimmer that your C... but my
custom build microchip is even faster... hehe... :-)
