You should be able to run many more zones than that on such a system. My guess is that you were experiencing slowness related to first boot. There are several things that thrash disks in the default config. Also, there may be some memory hogs. For example: - manifest import - fontconfig cache update - ppd cache update - postrun - webconsole (memory hog) How many of these run will depend on whether you are running Solaris or OpenSolaris and which release. Things are radically different in OpenSolaris today than with snv_40 (about 3.7 years old). snv_40 is probably pretty close to what you would see with Solaris 10, but I think even Solaris 10 may have improvements in this area compared to snv_40. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
