When an incoming exchange of an order cycle changes, the ProductsCache queries all affected outgoing exchanges to update them. It was creating a big collection of exchanges with duplicates and then calling `uniq`. That call was hitting a custom implementation of `eql?` which is very inefficient. And since `Exchange.eql?` is ignoring the order cycle id, it was probably filtering too many exchanges from the collection. Fixed bug: If two order cycles sell exactly the same variants to the same shop, the two outgoing exchanges are seen as equal. When the variants change, ProductsCache would only update one of those two exchanges, leaving one order cycle out of sync. This case is very rare. It only happens if there is a shop with two active order cycles selling exactly the same. The new uniqueness test looks only at the attributes that are later used to refresh the cache. I measured a page speed improvement from 90 seconds to 3 seconds (30 times faster).
Open Food Network
The Open Food Network is an online marketplace for local food. It enables a network of independent online food stores that connect farmers and food hubs (including coops, online farmers' markets, independent food businesses etc); with individuals and local businesses. It gives farmers and food hubs an easier and fairer way to distribute their food.
Supported by the Open Food Foundation and a network of global affiliates, we are proudly open source and not-for-profit - we're trying to seriously disrupt the concentration of power in global agri-food systems, and we need as many smart people working together on this as possible.
