Memory Tuning
Performance can also be improved by adding memory to your system. This is
especially true when working on larger models.
The system requirements for AutoCAD require at least 2 GB of physical memory
(RAM) for working in 2D. For creating and working with 3D models, at least
4 GB of RAM is required.
The size and complexity of a model often defines how efficiently an application
runs. If you notice increased hard drive activity, it means that physical memory
has been exceeded and data is being passed to a swap file (virtual memory).
A swap file is an area on the hard drive that Windows uses as if it were physical
memory (RAM). The swap file size is basically a limit which restricts the total
virtual size of the AutoCAD process. A good rule of thumb for configuring
your swap file is three times the amount of physical memory on your system.
This usually sets the limit high enough that AutoCAD doesn't run out of swap
space.
