[hibernate-dev] HSEARCH-1296

[Sanne Grinovero]

There is a "blackhole" indexing backend, which pipes all indexing
requests > /dev/null

Set this as an Infinispan Query configuration property:

    default.worker.backend = blackhole

Of course that means that the index will not be updated: you might
need to adapt your test to tolerate that, but the point is not
functional testing but to verify how much the SYNC option on the
JGroups backend is actually slowing you down. I suspect the
performance penalty is not in the network but in the fact you're now
waiting for the index operations, while in async you where not waiting
for them to be flushed.

If you can identify which part is slow, then we can help you with
better configuration options.
