When I set the Number of Products equal 50, what does it mean?
This value indicates how many products are exported by the feed generation script per one iteration. If this value is set to “0” – all products are exported at once. It is NOT recommended to set this option to “0” on low memory servers and/or if the products quantity to be exported is over 5,000. It is recommended to set this option equal “50” or “100” to ensure successful feed file generation. In this case, the products are exported in small portions by 50 or 100 items at a time, which does not cause additional load on the server.
DO NOT USE "Number of Products" equal “0” if you set "Yes" to export “Disabled” and “Out of Stock Products” options.
For example: "I have a low memory server and 10,000 (available in stock) products. How can I generate a feed file?" -
Set the "Number of Products" equal 50 or 100 (not more) and generate the feed file.
You will get the feed file with all 10,000 products.
