Dear Dynamicweb,

We see a performance penalty when using the product viewmodel as the property HandlePricesExclusively in our custom PriceProviders are not respected. Please see the code marked with red here:

        private List<PriceListViewModel> GetPrices(PriceViewModelSettings settings, IList<Product> products, ref bool pricesHasBeenPrepared, object @lock, Product product)
        {
            var context = settings.GetPriceContext();

            PreparePrices(context, ref pricesHasBeenPrepared, @lock, products);

            var prices = product.Prices.Where(price => DefaultPriceProvider.ShowPrice(price, context, product, false));

            var result = new List<PriceListViewModel>(
                prices.Select(price =>
                {
                    var priceRaw = new PriceRaw(price.Amount, price.Currency) { PriceSource = PriceSource.PriceMatrix };
                    var calculated = PriceCalculated.Create(context, priceRaw, product);
                    if (price.IsWithVat && !PriceHelper.PricesInDatabaseIncludeVat)
                    {
                        calculated.RawPriceIncludesVat = true;
                    }
                    calculated.Calculate();

                    return new PriceListViewModel()
                    {
                        Quantity = price.Quantity,
                        Price = CreateView(settings, calculated)
                    };
                })
            );

            return result;
        }

Hope it can be adjusted?

Best regards, Anders
