I use my computer for video editing home movies and pictures. I use Adobe Premier Elements 2. I noticed that it was taking a long time to render some video images, so I watched it with PERFMON. What I saw was the following. 1. Virtual memory was 1.45 GBytes. 2. Maximum working set was about 1.05 GBytes 3. Application page faults were about 40,000 per second!!! 4. System page faults were close to zero. Apparently what was happening was that Windows XP Media Center edition, was trying to maximize memory for the system, by not giving Premier Elements all the real memory it could use. Thus the 40,000 faults per second. All the pages were still in memory cache, so there were no pages written to disk. If the application had all the memory it used, the page faults would stop and the program would run much faster. Nothing else was running and there was about 1.2 GBytes of free memory. I know that other operating systems, (such as VMS) allow one to set the working set of an application. So my question is, can I set the working set for an application or process to 1.5 GBytes and how do I do that? I have all that memory in the system and it is just not being used. Thanks for any help.
