Virtual Memory


Per-Arne Almeflo

The vmem that is recommended by Microsoft is to have the same amount of vmem as you do ram. So in your case that would be one gig.

 

One theory about increasing vmem speed is to set your minimum to 15 megs below your maximum. By doing this the operating system pre-allocates your disk space and thus when you need to use virtual memory; you only need to write into the pre-allocated vmem block instead of also building the block as you require it. This used to make a big difference back when Windows NT 4 was the latest OS and 5400rpm disks were amazing.

 

There is no such thing as good performance with virtual memory though. If you need virtual memory then you would be MUCH better off by purchasing more ram. If you are using ironcad you can expect to see a speed reduction of at least 50% once you start consuming virtual memory.
