memory management and improved performance... [from a symantec email bulletin] >>>"Understanding Memory to Improve Performance Windows sometimes has a problem allocating the correct amount of memory to the disk cache. The disk cache or VCACHE is similar to the swap file. The disk cache swaps between active and inactive RAM while the swap file swaps between RAM and your hard disk (some hard disk controllers have a separate RAM cache on the controller). The Windows memory manager does not like free memory. Consequently, it will grow the VCACHE such that you will never have more than around 30 MB of unused RAM on your system at any time. VCACHE readily gives the RAM back to applications as they request it, but the lack of free RAM can be confusing, especially if you are using Norton System Doctor to monitor your RAM use. >>>Limiting the Size of the RAM Cache to Increase Physical Free Memory Regardless of how much RAM you have installed on your system, even with hardly anything running, you will find that only about 1/3 is available as free physical memory. A lot of RAM is being used and if you look at the Cache Memory Used sensor you will see where most of it is. Open and close different applications and watch the sensors to see what is going on. Notice how the cache grows whenever you close an application. You can limit the size of the cache and improve performance by editing your SYSTEM.INI file. Follow these steps to limit your cache file size: 1. Click Start and choose Run. 2. In the Open box, type SYSEDIT and click OK. The System Configuration Editor opens. 3. Click the SYSTEM.INI title bar. The SYSTEM.INI file moves to the front. 4. Choose the Search menu, and click Find. 5. In the Find field, type VCACHE and click OK. The cursor appears in the [vcache] section of the SYSTEM.INI file. 6. Add the following lines to this section, below the [vcache] label: MinFileCache=5120 MaxFileCache=8192 NOTE: (1MB =1024 kilobytes) NOTE: If the [vcache] section does not exist, create it, then add the above lines. These settings limit the size of the disk cache file to between 5 MB and 8 MB. This should be acceptable for nearly all systems, regardless of the size of the hard drive and the amount of RAM on the system. 7. Choose the File menu, then click Save. 8. Close the System Configuration Editor. 9. Restart the computer so the changes can take effect. After you complete these steps, you will notice how much more physical memory is free and a decrease in the memory load. As mentioned earlier, Windows will release the memory in the cache as applications request it. Nevertheless, having a very large cache has no benefit. It can cause Windows to swap additional information out to your hard drive swap file and slow down your system. Windows memory management is a complicated subject about which whole books have been written. We have only scratched the surface here. We hope we have shed some light on this enigmatic subject, and that you find this information beneficial." _____________________ note: i have made this vcache adjustment on my pc and noticed an immediate improvement on a 'memory load' sensor. the trick is to see if performance is noticeably impacted. i want to say, yes. i'm also running the memturbo program mentioned here recently, and i like the combination of the above vcache adjustment and the defragging and recovery of ram afforded by memturbo. any thoughts welcomed! :) mark
