Completely different technologies. Truss intercepts things in user space at the system call layer and blocks the application while it does some of that work; it's sort of like a debugger. Dtrace instruments arbitrary points in the kernel and writes the information into a circular buffer for another process to read. If you work hard at it, you can use dtrace to make things slow as well. (It has some built in self-protection that will kick in and start disabling your probes if the system gets "too slow.") -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
