The brief goals of the project are: 1. To support per-process hardware profiling, supporting performance measurement APIs like PAPI. 2. To support low-overhead `whole-system' profiling --- profiling the kernel and applications together. More information about this project is available under: http://people.freebsd.org/~jkoshy/projects/perf-measurement/ I've just started, so feedback from the community on the goals, directions and design of the project is welcome. Regards, Koshy
