If you only test your software on a 12-ASIN demo account, you never feel the pain a 400-ASIN brand manager feels every morning.
Inside Buy Box Checker, a brand page tracking 477 ASINs used to take 7.3 seconds to load and pulled 3.3 MB of data into the browser at once.
Today on production, that same 477-ASIN brand page loads in 3.6 seconds (about 2x faster for large brands) and is 55% lighter at 1.5 MB.
Two changes did the heavy lifting:
-> Large brand pages now render 100 rows up front and load the rest when you ask for them, instead of forcing your browser to chew through nearly 500 products on frame one.
-> Our Product Page Changes view dropped from 2.8 seconds to 2.1 seconds and is 65% lighter (1.8 MB down to 630 KB).
Small catalogs already loaded quickly, so you will notice the jump most if you manage hundreds of child ASINs across multiple zip codes.
When you open your daily ad or catalog dashboard, what is the slowest screen you still have to wait on?
