An excerpt from the answer:

There is also some discussion in the Quartz Users forum, with experience reports from developers who have used Quartz under similar conditions.

• Scalability & Performance - Jim Nichols is running a couple of thousand jobs clustered, and volunteers more information by e-mail
• Quartz performance - Stey Baptiste is running 2 million jobs a day, 10 jobs a second

Update 2015-01-12: Unfortunately, the links in the list above broke when the forum was moved, and I'm unable to find new working links. I'll leave the links anyway, in case they help digging out the info from archive.org or elsewhere. The official Quartz forum is now quartz-scheduler on Google Groups.
