Mutexes + . Reader/writer locks + . Condition variables + . Semaphores + . Tokens + . Adaptive lockings + +There are additional tests that measure the memory bandwidth under the +following conditions: + + . User memory-to-memory copying of data within a single thread + . User memory-to-kernel-to-user memory copying via pipes + between separate processes, as well as between separate + threads in the same process + +There are many options available for this module that can be put into +svc.conf files. See the Performance_Test_Options.[Chi] file for more +details. Some reasonable options to use to run the tests are: + + -v -B -s 15 + -v -n 4 -t 4 -s 15 + +You should experiment with other options as you see fit. Note that on +Solaris, you should always make sure that you have more than 1 LWP (by +using either the -B or the -n options) since otherwise the program may +get into an infinite loop due to the semantics of SunOS unbound +threads...
