            Bug ID: 55865
           Summary: Performance :Disable stale check by default in
                    HttpClient 4 and 3.1
           Product: JMeter
           Version: 2.9
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HTTP
          Assignee: [email protected]
          Reporter: [email protected]

Profiling JMeter, I noticed an important number of SocketTimeoutException being
triggered without any impact on response status.

I investigated it a bit deeper and find out it affected only HttpClient
implementations.
Looking a bit deeper, it is due to connection stale check which is enabled by
default.
This check sets a timeout to 1ms , see :
- org.apache.http.impl.io.SocketInputBuffer#isDataAvailable
- org.apache.http.impl.AbstractHttpClientConnection#isStale


I wonder if it's a good idea to keep it enabled by default as with high number
of Threads and throughput it means a huge number of Exception.
