我有一个托管在 IIS 8.5 Windows 2012 R2 机器上的 WCF (.net 4.5.2) 应用程序，它调用托管在另一台 IIS 8.5 Windows 2012 R2 机器上的另一个 WCF(.net 4.5.2) 应用程序。问题是我们有批量呼叫（比如说 200+）我的请求似乎正在排队。知道我做了什么特别的改进吗？两台机器都有 4 核和 4 GB 内存

编辑目前我已经尝试在机器配置中进行以下调整

<!-- <processModel autoConfig="true" /> -->
    <processModel autoConfig="false" maxWorkerThreads="1400" maxIoThreads="1400" minWorkerThreads="10" />

我还随机看到的一个问题是我收到 500 个内部错误。看起来呼叫永远不会到达第二台服务器。完整的错误跟踪是

log4net 数据库日志记录被发现是罪魁祸首。DB日志记录一一发生，因此我将log4net的bufferSize属性增加到10。如果有更好的改进建议，请告诉我。
