I think that made a lot more sense back in the days when 128MB of RAM was standard. If you have 16GB of RAM, and you're not using KDE nor a lot of VMs, are you ever going to really need all that RAM? As far as having the virtual memory provide a time window in which you can either kill the offending application or shut down in a half way decent manner, I'd think that given the slowness of swapping, 8GB would be enough for that purpose. Of course, all this is hypocritical for me to say, because I have 16GB of semiconductor RAM, and a 44GB swap partition :-) SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
