Reproduction steps:

1. Deploy the sample portlet
2. Add the portlet to page e.g. /web/guest/home
3. Perform the load test
   o Thread count = 100
   o Rampup time = 100
   o Loop count = 10
4. The server became extremely slow during the above load test, almost all threads were doing character encoding. Please see the attached thread dumps.
