[X3D-Ecosystem] Benchmarking JIT versus AOT CommandLine (X3DJSAIL)

[John Carlson]

New results.  I've combined all the validation code into one process.  I do
have less control, but I can still control which files get processed.

Only one process, JIT (well, find and xargs, that's not different)

real    3m2.537s
user    0m0.061s
sys     0m0.108s

This is quite an excellent result.  I hope that Don takes notice and starts
using <apply> in ant to speed up his code.  I am attaching code to run
validation (getting to -schematron).

One process, AOT compilation:

real    10m3.645s
user    0m1.044s
sys     0m1.457s


JIT appears to have a clear advantage for now.  I guess I won't look any
more into AOT.
