Hi All, Today for the first time I finally had my 9th graders use our classroom plone site to create content. As a single user, it seems fairly snappy, however when I had 10 students working simultaneously things were slow, taking up to 30-60 seconds to serve a page. When I had 25 students using the site simultaneously, things bogged down to almost a halt--taking 3-5 or more minutes to simply load a page or change user preferences. After first period I quickly went into the sit setup, deactivated dropdown menu and things were a bit quicker. And during lunch I deactivated diazo and the sun/rain theme and any other addon I knew I didn't need. But still, pages would take a 2-3 minutes to load with a class of 25.
The strange thing is that, I sshed into the server while this was going on and running htop it seemed that the processors rarely pegged 100%. Even after 30 minutes of this painful process, the load averages were .48, and .36! And, according to htop, the memory used was less than 1/2 the physical RAM available! This made me think that I've got something mis-configured on the server. Details: Plone 4.2.3 zeo/root install running in production mode on our districts backbone--very good network specs. It is running on an elder ProLiant DL380 G4, 2 cpu, dual-core Xeon CPU 3.20GHz processors (total 4 cores). There is 6 GB RAM. It is running Ubuntu 10.04. I've been using it for 4 years or so to host my plone site, recently upgrading to 4.2.3. I'm using Apache rewrite rules to serve on port 80. Computers accessing site from within district firewall (I wonder if I should have students access using the 10.x.x.x internal address and not via the external DNS name?). Here are further ZMI-reported specs: Zope Version (2.13.19, python 2.7.3, linux2) Python Version 2.7.3 (default, Dec 30 2012, 17:12:59) [GCC 4.4.3] System Platform linux2 INSTANCE_HOME /usr/local/Plone/zeocluster/parts/client1 CLIENT_HOME /usr/local/Plone/zeocluster/var/client1 Network Services ZServer.HTTPServer.zhttp_server (Port: 8080) Running For 22 days 23 hours 9 min 57 sec (main database was small: 548 MB and after packing went down to 273 MB) Any recommendations for areas to investigate? Things I could try? I really want to be using Plone with my students often, and I know I can't unless this nut can be cracked. Thanks for your work on Plone, David Groos -- View this message in context: http://plone.293351.n2.nabble.com/Should-my-class-be-maxing-out-my-4-2-3-setup-tp7562981.html Sent from the Installation, Setup, Upgrades mailing list archive at Nabble.com. _______________________________________________ Setup mailing list [email protected] https://lists.plone.org/mailman/listinfo/plone-setup
