AMZ Analyzer can process your Amazon wholesale list up to ~18,000/hr which is the maximum allowed by the Amazon API but typical speeds tend to vary from ~6,000-12,000/hr. Program speed depends on a lot of factors including your internet connection speed and routing to Amazon API servers so speed may vary.
Keep in mind that AMZ Analyzer will return ALL matching products from Amazon (unless otherwise set in Options) and each UPC/EAN/ISBN in your input sheet may have multiple results with different ASINs that represent completely separate sales listings on Amazon.com for the same product. This is important to understand when measuring speed because an Amazon wholesale list with 10,000 products may result in 30,000+ results! In this case speed should be measured based on 30,000 results.
