Jenny, these tests did not focus on the "number of arguments" effect. And indeed most of these probes have two parameters (lockid and lock mode), a couple have four.
We are currently building a small statistics keeping module that stores process stats of any kind in shared memory so an external program can monitor it. Will replace the USDT in use by call to functions from this module. Next step is to compare the DTrace results with these results. As I said in my blog, I do not care if there is a strong instrumentation effect as long as the behaviour of the application stays the same. I just want to make sure this is the case so our conclusions will be valid. -- This message posted from opensolaris.org _______________________________________________ dtrace-discuss mailing list [email protected]
