Hi Jim, Thanks for your reply, and that's good information. I actually did most of what you suggested. I started with dtrace and seems every system call takes longer to run on the filesystem when it is shared than not. So that's why I needed to understand what actually happens in the kernel.
Anyway I found color.d from Brendan's blog, which is quite helpful, it traces into all the way into every module. Thanks again. Sean This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
