Hi,

> However, is there a danger of setting the buffers too low?

Not really a danger. When VFP runs out of SYS(3050) space, it starts swapping to disk regardless of how much free memory is available. OTOH, higher values increase the risk for file mapping errors especially on long running (for weeks) applications with heavy memory usage. That's because a file map in Windows requires unfragmented, non-virtual memory. Heavy usage might fragment memory in a way that you don't have a larger enough chunk for the file map that VFP wants to generate.

Your application will be slower with a value that is too low and with a value that is too high. It's your choice. <g>
