I have always configured machines with the maximum swap space, figuring that it was better to have too much than too little (especially with 4mb of RAM in an 8 user system). I am currently configuring a 16 user system with a 310mb ESDI drive and 10mb of RAM. The max recommended swap space for the 310mb disk is 50mb. This appears excessive to me. Do I really need 50mb of swap space? The system will be primarily running WordPerfect 5.0, which requires an average of 600kb of RAM for each user. If all 16 users concurrently ran WP under a menu shell, it seems to me that I'd need to have 10mb of swap space available. The system will not run windows, graphics or other memory hungry apps, so the chances of any processes needing megabytes of core seem rather small. Am I oversimplifying my swap space requirements? How can I best determine the max amount of swap space that I'll need on a given system? -- Dave Hammond daveh@marob.masa.com uunet!masa.com!marob!daveh

Along these lines, how does one find out the ammount of swap space in use currently while the system is running. Not the total, but the free swap space???? Thanks!! bruce
