Planning a Workgroup Setting Disk-Management Strategy “Managing Swap and Dump” on page 425 provides some guidelines for estimating swap needs, but there is often no substitute for running the applications and seeing what happens. Example Here’s what we did to figure out how much swap would be used by the tools used to develop this document. We booted a workstation (an HP9000 715 running HP-UX 10.01 with 96MB RAM), started up VUE, opened one window, then started up all the applications one after another, using swapinfo (1M) to check swap usage each time. CAUTION The numbers that follow represent what happened on a given system on a given day; we are recording them only to illustrate the method. They in no way define the performance of the products or of HP-UX. Running HP-UX at run-level 3 took 19-20 MB of reserved swap. Transitioning to run-level 4 and opening one VUE window brought us up to 39-40 MB of reserved swap; this is shown in the first row of the table; subsequent rows show what happened as we started up the applications. Totals in the right-hand column are cumulative.
