20 A lot of this will obviously depend on CPU speed, number of
21 cores/threads, amount of memory and also, is it compiling on its own or
22 are other packages also being compiled and taking up CPU time or other
23 things using CPU time as well.  Here, AMD CPU at 4GHz with 8 cores. 
24 32GBs of memory and most packages built on tmpfs, except large
25 packages.  This is a recent few examples.

39 I left out binary emerges and such.  Oldest at top, newest at bottom.  I
40 suspect for the middle and most likely the bottom one, there was another
41 package compiling as well.  It's possible the top one was either on its
42 own part or all of the time. 
43
44 It's really hard to compare these things.  Even if our rigs are close in
45 speed/power/whatever, there can still be a lot of things that affect the
46 compile time.  I run KDE, watch TV from computer, have torrent software
47 that runs basically 24/7 plus other stuff running.  If you for example
48 use Fluxbox and have little else running, even with the same CPU and
49 memory, compile times will vary.

51 Does that info help?
