[En-Nut-Discussion] Off-topic - Building Nut/OS fast...very fast

Hi all,

I'm aware, that this is not directly related to Nut/OS, but the right
people to ask may be available here.

Building all Nut/OS libs and apps for all supported targets takes time
and I'm trying to figure out, where's the bottleneck. Upgrading to a
3GHz i7 and 12GB RAM helped, but I'd like to have more. Of course the
compiler does a lot of file I/O and the Hitachi drives I'm using are not
known for being fast.

Therefore I purchased an SSD (OCZ Agility2) and plugged it into one of
the SATA3 interfaces, expecting a real performance boost. I later
learned, that this SSD is not known for its high performance. But the
result was more than disappointing: Copying is now quite fast, but
compile time decreased by about 10% only. In fact this money was wasted.

The next idea is to get faster RAM. I'm currently using cheap DDR3-1600
CL9 9-9-24. For twice the money there are faster chips. But will it be
worth? Before wasting more money, I'd like to ask for your experience.
I'm not too familiar with PC technology.
