I've got a product based site and supercache does an awesome job of serving my pages up quickly. :)
My question is this...
I'm in the process of rebuilding the sidebar menu which is displayed on every product page. These product pages are custom post types and there is also a top level custom taxonomy page linked in the menu structure. Once I create the product page, there is usually no reason to go back and edit it. Everything is managed through my custom post template.
As I update the menu or tweak the template, how long does it usually take before one of my product pages gets refreshed in the cache? I know I can flush the cache, but I hate to do that as it takes a painfully long time for a non-cached page to load due to external api calls and I have 500+ custom posts. I would hate to do that to visitors each time I make a minor update to the template.
So does Supercache rebuild the entire cache directory at some point and how long does that take?
