First let me appologise if this information is avail elsewhere, but is there a product limitation as in number of products that can be created in an install.
IE. Some Ecommerce portals or solutions limit you to only 40 or 100 products, before i install nopCommerce i would like to know if there is a limitation like this.
There's no any limits on number of products. But we have some performance issues with a large number of products. A bit of customization can solve this issue.
10K products can't work fine, i think for now. for this condition you may need a dedicated server with at least 4G memory, maybe the cache mechanism of nopcommerce need to be updated,
a simple way to measure, check the usage of memory in task manager while opening the site. for windows 2003 : "w3wp"
