After a little work with git bisect I know the cause of this problem, however I am unsure of the correct solution. This problem was introduced in commit c7a3eba where a change is made to "Isolate each JSR ScriptEngine with separate PySystemState" to fix #2154. Simply reverting this commit appears to resolve this problem and causes no problems in the regrtests, however I don't know if this is a good idea. I'm still not completely sure why this change results in such a large performance issue here. I have a pull request (https://github.com/jythontools/jython/pull/82) to revert this commit for discussion, would be good if Jim could have a look at this.
