Manik Surtani updated ISPN-320:
-------------------------------

        Summary: When using a RspFilter, JGroups GroupRequest mode should always be GET_FIRST  (was: cache.get() takes some times  15 seconds to execute)
    Description: 
This was GET_ALL, which means we wait for all responses, regardless of what the RspFilter flags!  This was a huge bottleneck, resulting in the following:

cache.get() can get stuck for 15 seconds before returning. Trace level logging reveals: org.jgroups.blocks.GroupRequest - call did not execute correctly.


  was:
cache.get() can get stuck for 15 seconds before returning. Trace level logging reveals: org.jgroups.blocks.GroupRequest - call did not execute correctly.




The fix was simple: if a filter is used, set the response mode to GET_FIRST (as per the JGroups javadocs!)  Fix is in trunk.
