New OS Microbenchmark Suite
Bart Smaalders of Sun Microsystems has open sourced libmicro, a portable set of microbenchmarks designed to measure performance of basic system calls and library functions. This framework proved invaluable during Solaris 10 development as a way of identifying areas where performance was lagging behind other Operating Systems, as well regressions between Solaris builds. You can join the libmicro discussion at the OpenSolaris forums.
