- Can anybody explain what exactly determines the "reserved" swap space
- allocated by a program, and how I can reduce this number?
-
- I have a large application (running on Sun-4's under SunOS 4.1.x), and
- want to have several copies of the application running concurrently.
- Currently the swap space requirements are a major obstacle. According
- to "pstat -s" each copy of the application allocates 1.5Mb of swap and
- reserves 9.4Mb. Purify reports that the heap is around 3.5 Mb. To
- the untrained eye it appears that swap space is reserved for the
- entire text segment (size reports 6430kb text, 876kb data, 29kb bss),
- but never used. How can I eliminate or amortize this waste?
