Performance degradation when using REST API on WebSphere

XMLWordPrintable

      Description of problem:
      REST API calls are becoming significantly slower over time when Business Central is run on WebSphere.

      Version-Release number of selected component (if applicable):
      6.2.0 GA

      Steps to Reproduce:
      1. Run WasRestPerformanceTest from jBPM Integration test suite [1]
      2. See how test duration time is raising.

      Actual results:
      The same process run many times is becoming slower and slower. Here are the times to run 100 processes (in ms):
      9937
      20448
      23608
      29905
      45294
      60033

      Expected results:
      The execution should always take almost the same amount of time.

      Additional info:
      This is reproducible using both direct REST calls and provided remote client classes. The issue affects only REST interface. When you run the same processes using SOAP or JMS, you will see that there is no performance degradation over time.
