(aren't books about computer software always too old when they're printed?)

This is what more recent reiserfs does as well. Of course when you keep 
running old software you won't get the speedup. 

Anyway, I think this is becoming slightly offtopic..

I do agree that putting it on a RAM disk is the best thing, as long as the 
spool dir is not growing beyond certain limits. But sometimes bigger mails 
stuck in the spool directory, so they will fill up the RAM disc, destroying 
the small performance benefit you got.
