Publisher review:Optimize tep_get_tax_rate() method - Each time a price is displayed on osCommerce the tax rate for that product is queried. Problem:Each time a price is displayed on osCommerce the tax rate for that product is queried. Even if the user has set to not display taxes with price the tax rate is queried.Solution:Query for each rate one time as it is needed and then store it in session cache.What this contribution does:This code change will modify the tep_get_tax_rate() method so the first time a tax rate is requested it stores it in session. On every tax rate query it is first checked to verify if it's already in sesssion and if not will query / store in cache. If it is already in session it will return that value and save the database lookup.Result:Reduction in per page query count and faster execution times. Query reduction has been demonstrated to be around 75% savings on some pages.Tested on:8 setups with differing server configurations and osC setup. This change should not affect any other contributions.Install time:As fast as you can open a file, make one change, and upload.
