实体框架-字符串排序导致“等待操作超时”

当我使用Name排序时，我有以下查询导致"等待操作超时"。我怎样才能使它更快呢?Foods表中有8.5k行。

Expression<Func<Food, string>> byName = x => x.FoodTranslations.FirstOrDefault(y => y.Language.Code == CultureInfo.CurrentUICulture.Name).Name;
Expression<Func<Food, string>> byUdsa = x => x.Udsa;
var query = this.DbContext.Foods
            .Where(x => category == null || x.FoodTypeId == category)
            .Where(x => (string.IsNullOrEmpty(name) || x.FoodTranslations.FirstOrDefault(y=>CultureInfo.CurrentUICulture.Name == y.Language.Code).Name.Contains(name)));
        switch (order)
        {
            case 1:
                query = query.OrderBy(byUdsa);
                break;
            default:
                query = query.OrderBy(byName);
                break;
        }
        var result = new JsonFoodIndexResult();
        result.Foods = query.Skip(start)
            .Take(size)
            .Select(x => new JsonFoodIndex
            {
                Name = x.FoodTranslations.FirstOrDefault(y => y.Language.Code == CultureInfo.CurrentUICulture.Name).Name,
                Id = x.Id,
                Udsa = x.Udsa,
                Category = x.FoodType.FoodTypeTranslations.FirstOrDefault(y => y.Language.Code == CultureInfo.CurrentUICulture.Name).Name
            }).ToList();

query = query.AsNoTracking().OrderBy(byName);
