depends on your needs. that is, depends how much memory you need. My systems are all running on 1.5GB or less ram, and I have never noticed them using more then a few megs of swap, and even then they usually have more then 70% memory(RAM) available. also depends on how many disks you have and how they are arranged, ideally you should either have swap on a seperate disk or on a hardware raid array to improve performance..swapping can really drag down a system. this also depends on what your disk usage patterns are, maybe the system doesn't do much disk access so performance wouldn't be an issue.. 2 of my home systems.. 1 with 1.5GB and 1 with 1GB, the 1.5GB one is using 3MB of swap with 1.3GB available memory(disk cache), the 1GB system is using 0 swap with 751MB available memory(disk cache). my laptop has 256MB, it's using 5MB of swap with 195MB available memory (disk cache again). it can't hurt to have more swap partitions, but most configurations won't need it. If you have such a system that it needs to dig into a lot of swap I'd reccomend upgrading the memory or splitting the load accross multiple systems for better performance. if you configure the system with LVM it can be pretty easy to re-configure the setup to allocate more space for swap, or you could use swap files(big performance hit I hear). nate (linux user since '95) -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
