For the size of image you are processing you would benefit hugely from more RAM.
Most of your 256Mb will be consumed just by WindowsXP before WinTopo even gets a
look-in.
If your system runs low on RAM while WinTopo is processing then WinTopo uses the
hard-drive swap-space as extra RAM in order to try to complete the process.
However, hard-drive swap-space access is about 1000 times slower than RAM, and
so the processing can take a long time when that happens.
Fortunately, RAM is very cheap these days and you can buy a Gb for just a few
dollars. Upgrade your RAM - it should make a lot of difference to the speed of
your machine when processing large images.
