It's just demo, we are not able to make it with database of one milion products.
sir, you misunderstood me. not asking of demo large database, but what was max number of items you have tested performance of grandnode? hompage text mentioned 'fast', so I assume you made some kind of tests. Do you have any results to share with community?
Yeah, we've made tests with database of 50,000, 100,000 and 500,000 products, but today I would be able to show only raw numbers. And without screenshots, graphs, I suppose it won't convince you, we will prepare detailed comparison on new website someday.
