I haven't seen one, but it would be great to have this on the wiki where 
everyone could post what they're seeing & using.

Maybe the autobuilder has some useful statistics 
(http://autobuilder.yoctoproject.org:8010/)?  Of course, you'll have to 
be careful to determine whether anything else was running at the time of 
the build.

On a related note, I have been wondering whether I would get the bang 
for the buck with an SSD for my build machines.  I would guess that 
building embedded Linux images isn't a typical use pattern for an SSD. I 
wonder if the long write & erase durations for FLASH technology would 
show its ugly face during a poky build.  I would think that the embedded 
micro inside the SSD managing the writes might get taxed to the limit 
trying to slice the data.  I would appreciate anyone's experience with 
SSDs on build machines.
