Is there a magic number, or some guide as to what is a realistic limit for the number of categories a Magento catalog can contain?

A project I'm working on will need to feature some 9000 or so categories - is this an achievable number in Magento Community Edition?

I know there are concerns with large product catalogs, but I can't find any information around large category sets.

  • As a heads up, working on a menu system and category collections massively eat time and memory if you don't do proper collection manipulation. They're still quite resource intensive if you do it right. – Fiasco Labs Dec 22 '15 at 17:12
  • @FiascoLabs That's a good point - can you elaborate what you mean by collection manipulation? The majority of the categories required are of a specific type, and these need not form part of the main menu system. (How to go about this is a question in itself). – BrynJ Dec 22 '15 at 17:18
  • Loading collections within foreach loops is one issue that comes to mind. – Fiasco Labs Dec 22 '15 at 19:07

There is no magic number, personally I've built ecomm solutions that have 100s of thousands of products, and 1000 of categories using CE. Long as you have a proper server, caching and optimizations it'll run practically the same as if you only have a handful of products and categories.
