Есть вот такая функция
// *****************************************************************************
// Purpose gets extra parametrs
// Inputs $productID - product ID
// Remarks
// Returns array of value extraparametrs
// each item of this array has next struture
// first type "option_type" = 0
// "name" - parametr name
// "option_value" - value
// "option_type" - 0
// second type "option_type" = 1
// "name" - parametr name
// "option_show_times" - how times does show in client side this
// parametr to select
// "variantID_default" - variant ID by default
// "values_to_select" - array of variant value to select
// each item of "values_to_select" array has next structure
// "variantID" - variant ID
// "price_surplus" - to added to price
// "option_value" - value

При 130.000 товаров и у каждого порядка 5-10 параметров.
Есть какие нибудь идеи для оптимизации этого пиздеца?
