Executor.execute very slow.

[Santhosh Kumar <sa...@gmail.com>]

Hi - In our project we are using Apache http client and fluent jar to the
hit AWS cloud endpoint where in we pass request and get the response back.
Code snippet is given below.  But the performance is very slow. Connection
establishing and socket read takes more time. Can you please suggest if
there is any way to optimize this?

               Executor executor = Executor.newInstance(httpClient);
//Executor executor = Executor.newInstance(buildHttpClient());
Response channelResponse = null;
Request httpRequest = Request.Post(serviceEndpointUrl)
.addHeader("Service", wizConnectRequest.getTransCode())
.addHeader("consumer", channel).addHeader("Async",
String.valueOf(wizConnectRequest.isAsync()))
.addHeader("TimeOutPeriod",
Integer.toString(wizConnectRequest.getTimeOutPeriod()));


channelResponse = executor.execute(httpRequest.useExpectContinue()
.connectTimeout(endPointTimeout) //in milliseconds TODO is it not managed
through the Spring???
.bodyString(request, ContentType.DEFAULT_TEXT));

I have attached the performance snapshot using Dynatrace tool where the
total time taken is 589.62. Please let me know.

Regards
Shan

Hi,

You should make sure to reuse your HttpClient instance.
