Setting the
kernel.hz_timer = 0
in the /etc/sysctl
will probably help at least some but your probably going to have to do a
detailed memory analysis to see how much memory is REALLY needed with DB2

Yep, you can run it, but everytime I bring up KDE, it takes about 40%
of our 60 MIP processor. There is very little that you ever need a
desktop manager for that can't be done via command line. But it is
really nice to have as a fall back to install some product.

I've been working with a few installations with less than
stellar performance. Seems like NFS under linux is a culprit.
As well as VM and it's 2GB constraints.
