Question

I was speaking to a developer recently who said that no magento CE full page cache worked perfectly even with a default install.

my experience of this is the same. <

1 problem what you might have with aoe_static is, that currently the extension doesnt log products so statistics in backend about viewed products are not updated. this was added recently as TODO note into the github.

problem with varnish and magento cache is, that magento cache parts of pages, blocks and varnish does cache whole pages. so even though phoenix solution have observers in place and reset varnish accordingly on product/category update, you still have blocks in magento what have to be reseted. aoe_static try's to solve this, but it does only for visible blocks on the page. but other parts of magento, as layered navigation, might be reseted as well internally on product/category update, but than are not reset in varnish. there are 2 solutions. either identify every part of magento on frontend whats not reset after product/category update and apply aoe_static solution to it. that would mean you would have to load layered nav via ajax. or the second solution is, to add more logic into phoenix extension to invalidate more varnish pages.

i have couple of custom extensions (pages what display products) and i build logic to invalidate those extensions each time product/category is updated. now im working on search, as this needs to be invalidated as well, but the complicated part is, to work around blocks and cache invalidation logic.

overall, proper cache invalidation is one of the hardest part of web development.
