In a real-time environment, frequent demand paging can decrease performance.
Demand paging allows memory to be shared among multiple processes. In a demand-paging environment, pages from one process are discarded and removed from memory when memory is low. You can turn off demand paging for the entire system by using the Config.bib file. You can also turn off demand paging for an individual DLL by using LoadDriver or by creating a file system driver that does not support demand paging. When demand paging is turned off, all the code for a module is loaded into memory and never discarded.
