We are trying to quantify the amount of physical memory that is consumed by Solaris versus the number of file systems which are mounted within a ZFS pool. This is for a situation where there would be 15,000 to 20,000 file systems. Has anyone measured this? I''m assuming U2 or U3 of Solaris 10 (SPARC). If this has changed dramatically for recent nevada builds that would be interesting as well. regards, bill This message posted from opensolaris.org
