Well I gave it a try, and it seems my assumptions were = somehow true.
Here is what I got when running one of my apps in sin= gle shot mode (load, run, terminate):

default p= ython distribution
total time 9.022s
ENOENT's c= ount=C2=A07377

pyrun
total t= ime=C2=A08.455s
ENOENT's count=C2=A03064

=
So, it indeed failed much less to open files, but I guess this d= idn't make that much difference after all (500ms).=C2=A0
Perh= aps it is because this app has some external dependencies (22 to be precise= ) not bundled on pyrun that had to be scanned by the interpreter anyway. If= by any means we could bundle them all the same way, than it could bring a = much higher performance gain. But I guess it is not really safe-feasible.

We have been providing binaries for Raspberry Pis for quite
some time, but without official support, so they are not listed
on the product page.

If you run install-pyrun on a Raspi, this should install PyRun
for you. I'm not sure whether it'll work on the new Raspi 2.
We'll probably add one to our build farm in a few weeks.

These are the direct download links if you want to give it
