i just retested on one spare machine:
Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz

you need ~12 tmpfs and a
"make clean; make -j25"
runs in 310 secs. it seems to last very long
to generate the image-files, compiling itself is fast.

tomorrow i will test another board with 4ghz AMD.

my idea was, that people of the community can "spend"
cpu-time and run builds for only 1 arch after each checkin.
