What is the performance overhead of running STAF?
As a general rule, STAF takes up very little system resources. A typical STAF installation is about 10-30 MB (depending on whether you use the installer with the integrated JVM). STAF’s in-memory size (without any additional external services) is about 2.5-5 MB (depending on the platform). On an idle STAF system (i.e., one in which there are no requests currently being handled by STAF) STAF consumes 0% CPU on a Windows system and a VERY limited amount on unix systems. On unix, we have a thread which wakes up once a second to see if any STAF processes have completed. STAF was designed to consume as little system resources as possible, as we know that people want their test systems as close to clean-room conditions as possible.
