Hello all, As you know, i''m making some "screencasts" about a few solaris features. That screencasts is one point of many tests that i''m making with solaris 10. Now, with some tests with dtrace, i have saw a interesting point: the creat64 and unlink system calls are uniforms (times) on ZFS, but have some strange times on UFS (standard deviation). I have two simple questions: [b]a)[/b] The filesystem utilization can be the problem? I mean, the UFS filesystem is 86% in use, and the ZFS is almost empty. [b]b)[/b] Can that difference be structural? I mean, have a explanation on the design of the two filesystems? If yes, can you quickly explain that to me (links to opensolaris code)? So i can put it in the blog (screencasts). Thanks very much for your time. The url: http://www.posix.brte.com.br/blog/?page_id=30 Leal. This message posted from opensolaris.org
