39 The ones I listed before also jumped in compile times.  As I said tho, I
40 don't know if other things compiling affected that time.  Still, it does
41 seem to have increased but I remember when I was on my old single core
42 rig with just a few GBs of memory.  As time goes by, software gets
43 bigger therefore takes longer to compile.  Yours from the 4th to the 6th
44 in the list sure does increase.  That's 8 to 10 times longer roughly. 
45 That's a large difference.  A true test, emerge something interesting
46 all by itself.  See what it comes closest to, the old times or the newer
47 and longer times.

49 I suspect this is changes in features of software and could even be
50 related to gcc or some other tool compiling uses.  It is a interesting
51 jump.  I don't think you are alone in this.  Maybe someone else will
52 post their info.  For those interested, genlop -t <package name> is how
53 to get this info.

55 BTW, I don't use systemd so I can't list mine.  ;-)
