Cs-Cart Stability And System Requirements To Work Good


i'm planning to open a multistore with more or less 10000 products shared between all of them and a number of online-stores which will go between 20 and 100.

Assuming i'll split the application server and the database server, each one with his own specifics ( E.G: Two different instances on the Amazon Web Services, or any VPS out there ) i wish to know if someone had troubles keeping it online, how much resources does it use such as RAM rather than CPU or physical memory.

Someone who successfully work with 50+ stores online is able to reply me a feedback of his/their server specifics in order to make me aware of what i'm going to face?

It would be great !

Best regards
