Tuning the Kernal

[WSHB Operations Eng]

I need some advice on kernal tuning for SCO Xenix 2.3.2 on a 20 MHz
machine with 9 MB memory. 

Until recently my machine has been most heavily loaded during the day 
with only a few uucp connections and a login or two happening at night. 
Now - as the night crews are becoming more familiar with the machine, 
we start processing more reports with cron and all three modems 
fire up - I have started running into the maximum process limit. 
I don't really think there is a big problem of running out of memory. 
My swap space is huge and the 9 MB of ram should handle bunches of stuff 
anyway. 

I have looked at /usr/sys/conf/master and found that procs is set to 60.
As I have never had to tune a kernal before I am curious what will happen
if I just raise this limit to 120 and re-link. Are there any other things 
I should change at the same time to prevent bad things. I have included 
the tunable parameters list.

(Does anyone have recomendations for a good book which explains what all
of this stuff does?)
