Hello,
I have been testing nopcommerce for a new ecommerce site and was for months running 2.6 but won't go live with it because it's painfully slow. I already went through implementing suggestions to speed up things a bit but so far no luck. I was really excited to see 2.7 came out which is touted to be optimized for performance. But after the upgrade, I didn't see any improvement.
Here's the website running on nopcommerce 2.7 http://www.baghangersonline.com
In comparison, here's another website running on the same server. The site is built using the old, first generation Commerce Starter Kit (CSK). http://www.epektos.com
As you can see, the older site smokes nopcommerce in terms of speed.
I'm really rooting for nopcommerce since I thinks it's one of the feature rich shopping cart solutions out there and it's free to boot, thanks to selfless contributions from people here. I hope I am just missing something, a misconfiguration probably? Hope to hear suggestions from anyone.
Thanks and more power to NOP.
