Its much the same here, except that the T420 laptop is 3-4 times faster
than the AMD Dual Athlon for decent sized Java and C compiler runs while
the RPi is about the same speed as an OS/9 system I used to have, that
ran on an 8MHz 68020.

The other thing I really notice is when I'm writing or debugging C or
Java, the T420's first compilation run of the day typically takes 3-4
seconds and all subsequent runs are under a second. This seems to be due
to memory caching: the first run pulls compilers/linkers/JVM/make or ant
into RAM along with most of the source files and they stay resident until
doing something else with large memory requirements kicks them out.
