Understanding fingerprint measurement in java garbage collection

Question

I am trying to understand java garbage collection. There are four dimensions to garbage collection: here :

• Throughput
• Suspense
• Footprint
• Efficiency

Footprint is a workflow set measured on pages and line caches. On systems with limited physical memory or in many processes, the fingerprint may dictate scalability.

I can understand the other three, but what is it Footprintand how to optimize it?
