Thanks for the info. I'm surprised that I never thought of doing that before 
I emailed you. I did search Google, though; obviously not very well.

So, in my fiddling around with the 2 programs, I managed to speed my 
computer up a bit.

The 1st thing that I did was make all of the root user processes 19 by 
default. When I'm compiling or doing whatever as root, then I'm not in a 
rush, & I am willing to make it go slower so that user eugene can surf the 
web faster. To set this only for root, I entered the following line in 
/etc/profile where the prompt was set for root:
/usr/bin/renice 19 -u root

& the 2nd thing that I did was add the following in .../program/soffice
# execute soffice binary
# there is a bug in solaris sh that prevents the use of "$@"
# because it cannot cope with spaces in directory names
if [ "X${plugin_mode}" = "Xtrue" ]; then
        SAL_IGNOREXERRORS=true
        export SAL_IGNOREXERRORS
        exec nice -n 19 "$sd_prog/$sd_binary" -plugin "$@"
else
        exec nice -n 19 "$sd_prog/$sd_binary" "$@"
fi

For soffice, all I did was insert "nice -n 19" to the code that was already 
there. This is useful, because you can run quickstart & have it run @ a low 
priority.

I hope that this is helpful for people. I've noticed that my system runs 
much smoother even when OpenOffice.org is loading up, & in some cases even 
when something is compiling.


Sincerely, & with thanks,
Eugene T.S. Wong
