如何提高WCF的执行效率

Answer 1

面我各处配置： <bindings>
<customBinding>
<binding name="myMexTcpBinding">
<binaryMessageEncoding>
<readerQuotas maxDepth="32" maxStringContentLength="819200" maxArrayLength="1638400" maxBytesPerRead="409600" maxNameTableCharCount="1638400"/>
</binaryMessageEncoding>
<tcpTransport maxBufferPoolSize="524288000" maxReceivedMessageSize="65536000" maxBufferSize="65536000"/>
</binding>
<binding name="mybinding">
<binaryMessageEncoding>
<readerQuotas maxDepth="32" maxStringContentLength="819200" maxArrayLength="1638400" maxBytesPerRead="409600" maxNameTableCharCount="1638400"/>
</binaryMessageEncoding>
<tcpTransport maxBufferPoolSize="524288000" maxReceivedMessageSize="65536000" maxBufferSize="65536000"/>
</binding>
</customBinding>
</bindings>
<service behaviorConfiguration="MyBehavior" name="Services.BaseDataManage.BaseDataManage">
<endpoint address="" binding="customBinding" bindingConfiguration="mybinding" contract="Services.BaseDataManage.IBaseDataManage">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="customBinding" bindingConfiguration="myMexTcpBinding" contract="IMetadataExchange"/>
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8802/BaseDataManage/"/>
</baseAddresses>
</host>
</service>
<behavior name="MyBehavior">
<serviceMetadata httpGetEnabled="false"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
<serviceTimeouts transactionTimeout="23:59:59"/>
<serviceThrottling maxConcurrentCalls="1000" maxConcurrentSessions="1000" maxConcurrentInstances="1000"/>
</behavior>
[ServiceContract(CallbackContract=typeof(IBaseDataCallBack))]
public partial interface IBaseDataManage
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerCall)]
public partial class BaseDataManage : IBaseDataManage
wcfbindingbehavior
性能原：
1、事务：事务需要同步文发阻塞若达连接高值需排队甚至超；解决：支持事务与非事务服务同服务；
2、调：调需要采用独立线程或线程池执行调操作否则能调掉线、间运算、超等素造直占用或间占用尽能设计让服务IsOneWay=true；
3、服务器资源允许情况：采用InstanceContextMode.PerCall,UseSynchronizationContext=false,ConcurrencyMode = ConcurrencyMode.Multiple种能并发应用
4、吞吐量配置我知道配置文件何配我自写ServiceThrottlingAttribute继承AttributeIServiceBehavior配置连接数 MaxConcurrentSessions （WCF默认10)文实例数 MaxConcurrentInstances待处理消息数或调数MaxConcurrentCalls（WCF默认64)
5、仅我配置能些解释确通改并发性能都提升由于我工作流服务目前高3000-5000工作流同运行并没发明显阻塞
