We just moved a production Perl CGI website from the global zone on a 4 core/16 cpu T2000 (with no other apps) into a 4 cpu sparse-root container on that same T2000. The CPU load during user hours on the T2000 had reliably been running between 1.0 and 1.5 since roughly late May; but now the container is saturating all four cpu's it has and is clamoring for more (loads of 4.00+).
Two other changes we did were moving the website filesystems to ZFS, and upgrading to kernel 120011-14. The website is running IPlanet 6, SP5, and is using the inherited Perl 5.6.1 from the global zone. The website/CGI apps themselves did not change, but the short-lived CGI scripts are responsible for taking up the extra CPU time (as reported by dtrace): # shortlived.d Tracing... Hit Ctrl-C to stop. ^C short lived processes: 48.254 secs total sample duration: 34.453 secs Any idea why the CPU load of the CGI scripts would shift so drastically? -Philip This message posted from opensolaris.org _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
