Welcome Salvador.

Interchange is a lot of hard work. We have 8000 items all on each of
three sites and I pack and answer the phone too.

Now we have returned to the old Departments, Groups and Brands type
navigation as we have suffered under google. They say that google likes
structure.

Anyway by optimizing as much as I could, I am now getting a reasonable
report from all those speed testing sites. You may have to sacrifice
content to get it down to our 2.7 seconds. This is the main reason I am
upgrading, hoping it will increase sales. If that happens I will report
back.

Good luck.
