I do very much care about the build time. I was thinking of cross compiling
on my
ancient desktop then moving it to the Pi ?

What are the specs of your ancient desktop?

Well.. like I said pretty old my bios is:
cat /sys/class/dmi/id/bios_date
07/05/2013

and lscpu shows:
Architecture:          x86_64
CPU(s):                4
Thread(s) per core:    2
Core(s) per socket:    2
Vendor ID:             GenuineIntel
Model:                 60
Model name:            Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz
CPU MHz:               3389.375
CPU max MHz:           3400.0000
CPU min MHz:           800.0000
BogoMIPS:              6784.89

and free -h shows:
             total       used       free     shared    buffers     cached
Mem:          7.5G       5.2G       2.3G       341M       163M       2.1G
-/+ buffers/cache:       2.9G       4.6G
Swap:         902M         0B       902M

it's not a bad system I just want to start messing with a Pi :-)

Thank you for all the pointers and advice.
