Question

我们正在开发一个使用Microsoft Dynamics CRM连接到XRM SDK的系统，它的服务器端构建在.NET MVC上，前端端基于 Angularjs < / p>

我们在API响应中面临延迟问题，例如。登录API至少需要 1.8秒来检索成功或错误响应，而且这个API是最快的。

其他API甚至更慢，我们试图抓住这种缓慢的来源以便修复它，但没有运气。它是XRM SDK，API还是CRM本身。

如果你能提供帮助。

var cols = new ColumnSet("exdyn_employeecontractid", "exdyn_contractstatus");
            var secondEntityCols = new ColumnSet("exdyn_companyagreementid", "exdyn_agreementstatus");

            var filter = new FilterExpression
            {
                Conditions =
                {
                    new ConditionExpression
                    {
                        AttributeName = "exdyn_employeeid",
                        Operator = ConditionOperator.Equal,
                        Values = {model.EmployeeId}
                    },
                    new ConditionExpression
                    {
                        AttributeName = "exdyn_contractstatus",
                        Operator = ConditionOperator.Equal,
                        Values = { 3 } // approved {2} signed
                    },

                },

                FilterOperator = LogicalOperator.And
            };
            var secondFilter = new FilterExpression
            {
                Conditions =
                {
                    new ConditionExpression
                    {
                        AttributeName = "exdyn_agreementstatus",
                        Operator = ConditionOperator.Equal,
                        Values = { 2 } // active {2}
                    }
                }
            };

            var entity = _organizationService.GetEntityCollectionWithJoin
                ("exdyn_employeecontract", "exdyn_companyagreement",
                "exdyn_companyagreementid", "exdyn_companyagreementid", JoinOperator.Inner,
                cols, secondEntityCols, filter, secondFilter).Entities.FirstOrDefault();

它最有可能是CRM / API。你应该能够用像Fiddler这样的东西测试一下，看看正在发出的请求，并确定缓慢发生的地方。例如，以下是使用旧版SDK查询CRM在线沙箱：

var connection = CrmConnection.Parse(@"Url=https://ORG.crm.dynamics.com;Username=USERNAME;Password=PASSWORD");  
_orgService = new OrganizationService(connection);

_orgService.RetrieveMultiple(new FetchExpression(@"<fetch><entity name='account'><attribute name='accountid'/></entity></fetch>"));

检查提琴手，您会看到以下内容：

客户端有大约4个单独的HTTP请求，需要认证大约需要1.5秒（在这种情况下，它纯粹是O365用户，不使用ADFS）
最终的HTTP请求是返回5k帐户ID的实际查询。返回需要约5秒钟。

如果您对代码进行计时并与实际的HTTP请求进行比较，您可以看到花费的时间，但我敢打赌它将是请求，而不是SDK。

您可以采取一些措施来尝试优化查询：

仅返回所需数据
限制联接数量
确保插件未在要查询的实体的RetrieveMultiple上运行。
验证一次并重复使用＆＃34;连接＆＃34;。（根据您使用的SDK版本以及该SDK的哪些部分可以通过不同的方式完成。CrmServiceClient现在默认缓存，其他连接字符串具有Service Configuration Instance Mode等选项。

使用XRM SDK的Dynamics CRM速度缓慢？
