Architecting a Solution with many Sites within a Site (Chapters) - How many sections can Craft Handle? I am working on a plan for a site build that includes national content as well as many chapters' content. The latter has a number of requirements that are leading me to using separate sections including a structure for general pages and news, and events channels. 

So looking at 3 sections per chapter and starting with around 20 chapters with more to come over time.

I am not worried about the manual setup of these (albeit it's not ideal); however, I am concerned about hitting limits either in the interface and/or performance of Craft that I just may not be as familiar with.

As chapter numbers grow, will this be too many sections for Craft to handle?

Probably not.  I suspect as your section list grows to the multi-thousand section range (if it will ever get that large), you'll start to run into MySQL/environmental limitations rather than any Craft ones.  But if  you do run into any UI/architectural limitations, we'd love to hear about them.

In the upcoming Craft 2.3 release, we spent a great deal of time addressing UI scaling issues around Structured Sections and Categories when they start to approach the multi-thousand range, but we've seem installations with several hundred thousands of Channel entries/assets/users running just fine.
