IIS中的大量连接

Question

I have hosted our web service on one of the IIS server. Many of our web service calls are failing for that server. Load on that server seems to be normal despite no of connections.

Below are the statistics

Total Reqest/Sec - 150~200
Request Execution Time - 0-10ms (mostly 0)
Request Executing - 0 - 5
PipeLine Instance Count - 0
Web service -> Current connections - 8k~10k
%processor time - 1~2%

I do not see major issue here apart from number of connections. How can I reduce the number of connections since web service is mostly returning the static data.

Or is there any other reason that to this?

Answer 1

In the service client, make sure you are closing all the connections that you are making. We had similar issue, and resolved it by just closing the proxy connections on client side.
