I have done a lot of plain "make world" in these days using this little
scripts:
#!/bin/sh
cd /usr/src
echo -n "---- Start Make World : " >>/root/world.log
date >>/root/world.log
cd /usr/src
make world >/dev/null && echo -n "---- End Make World : "
>>/root/world.log && date >>/root/world.log
chmod 777 /var/mail
chmod 555 /usr/share/man/cat?
a) ---- Start Make World : Mon Nov 17 10:06:17 GMT 1997
a) ---- End Make World : Mon Nov 17 11:56:31 GMT 1997
b) ---- Start Make World : Wed Nov 19 10:40:41 GMT 1997
b) ---- End Make World : Wed Nov 19 12:30:21 GMT 1997
c) ---- Start Make World : Fri Nov 21 03:24:35 GMT 1997
c) ---- End Make World : Fri Nov 21 05:16:52 GMT 1997
d) ---- Start Make World : Fri Nov 21 18:15:36 GMT 1997
d) ---- End Make World : Fri Nov 21 20:09:23 GMT 1997
e) ---- Start Make World : Sat Nov 22 15:30:40 CET 1997
e) ---- End Make World : Sat Nov 22 17:29:29 CET 1997
f) ---- Start Make World : Mon Nov 24 02:38:05 CET 1997
f) ---- End Make World : Mon Nov 24 04:27:21 CET 1997
All the line minus f) was obtained using :
/dev/sd1a on / (local)
/dev/sd1s2f on /usr (asynchronous, NFS exported, local)
/dev/sd1s2e on /var (asynchronous, local, noatime)
procfs on /proc (local)
This last, f), one was obtained using :
/dev/sd1a on / (local)
/dev/sd1s2f on /usr (asynchronous, NFS exported, local)
/dev/sd1s2e on /var (asynchronous, local, noatime)
/dev/sd0s2e on /usr/obj (asynchronous, local, noatime)
procfs on /proc (local)
I though I can achieve better result if I use two disks for the /usr/obj
and /usr/src, than only one for both. But in reality the gain in the
time is little and I am not so fast as other people here in the list
that use slower hardware <sigh>.
I use -pipe -O in the make.conf and I do plain "make world".
My configuration is :

In the kernel (from c to f )I have used :
options AHC_TAGENABLE
options AHC_SCBPAGING_ENABLE
options AHC_ALLOW_MEMIO
All the make world except one (made from an xterm) was made from console
without any other relevant task in the background (single box not
connected to the net)
Any suggestions to speed up my box ?
Another funny thing :
Adaptec support told me one time to disable disconnection of the drives
(for correcting some incompatibility with matrox card under Win95) but
if I leave them disconnected with the 3 option above I can see fireworks
during a make world ... Is it correct ?
Thanks everyone for attention and sorry for the long posting...
