AbleCommerce Shopping Cart Software

I want to build a super market on Internet. So, I need an system with high performance.
I saw that AbleCommerce is high performance. But, my boss still need a litle comfirmation.
Can you show me some certificates about AbleCommerce performance?(it may be a link about AbleCommerce performance certification or anything!)

Thank you so much!

When it comes to high performance and scalability there are too many other factors to be fine tuned than the application itself. Optimizing the application for high performance is just one part of a much bigger picture. If your application is running on a poorly configured system you can't get good performance. If your database server is loaded with lot of other services you can't expect good performance. What are your hardware specs; Are you running in a load-balanced cluster or on a standalone server; ... there are so many things to consider.

As far as Ablecommerce is concerned it is architectured to be highly scalable and performant. In some other threads in the forum you may get some statistics as well.
