This may grab some interest from those running dog-slow servers

Then I got hooked on using multiple xterms; the rest is history.)
Unless I'm having severe delusions, by tweaking the NICE
priorities on a bunch on std and added binaries, on my 400MHz.
Kayak (with gnome-lite), I'm getting good performance. Later
this year (or whenever hands can help me rob my junk Kayak's
memory) I'll boost the SRAM from 192 to 512MB. That ought to
allow me to run even more smoothly.
The tuning so far has been done entirely by-hand. One example is
setting the sendmail priority from a nice of 0 down to 7. I've
nice'd xload down to 20; increased firefox to -17, and so forth.
top runs very well niced at 19 with "-s5". And it does keep the
5-second update fairly well. I don't care about knowing what
the system is doing every second (or default two seconds). But
it's nice to know how things are generally going. ....So now for
some questions: I'm thinking of writing a script that, once it
know that X is running (and gnome/kde/<<whatever>> is in the
table) will re-nice everything to my tastes. Is there any way of
setting things to run at a lower or higher nice value, other than
by-hand or by-script? Since I'm not that concerned with having a
port built in K minutes or N hours (or M days :-(), can I set gcc
down to 5 or 7 or whatever value? Any kernel hackers or *real*
sysadmins who can clue me in?
If my backup server is still running in a few month, I'll write
up an article on "system tuning" and put it on my BSD site.
thanks for any/all thoughts,
Seems like /etc/login.conf is the winner if you're looking into setting
the global priority to something a bit lower :).. but if everything runs
at the same priority won't all your processes be slow at the same speed :)?
