I've done some pi compiling.

I protoed the code on my twin core X86 desktop, then transferred it to
the pi and compiled it. Now my desktop aint  brutal - its an entry level
motherboard with a twin core entry level processor, and the compilations
was dine across the 100Mbps network as far as file reading and writing
went - but the pi zero took about ten times as long to compile on the SD
card...
