Several things with this post are strange, maybe wrong? First, the pthread lib on FreeBSD is NOT kernel threads, which Sun does have, so the test is not valid to begin with. Second, you don't mention if you were using an SMP kernel, with SMP turned on. If you were, and you were running more than one process, you _would_ have noticed a difference, but not in the one-process test you show. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic, both FreeBSD (301) 220-2114 | version 3.0 current -- and great FUN! ----------------------------+-----------------------------------------------
