Rajith Attapattu commented on QPID-3659:
----------------------------------------
It is indeed due to not being quoted properly.
However due to the really convoluted syntax there is an increased risk of
people screwing up.
If the default value is false then it's a different matter, but in this case
the default value for TCP_NODELAY is true (from the 0.14 release).
Therefore any mistake by the end user will turn off TCP_NODELAY.
> Java client mishandles tcp_nodelay when specified as part of the broker URL

> Key: QPID-3659
> URL: https://issues.apache.org/jira/browse/QPID-3659
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: 0.15
> Reporter: Kim van der Riet
>
> When tcp_nodelay is set as part of the broker's address, the performance of
> the client drops badly, no matter whether the value is set to 'true' or
> 'false'. I assume that the parameter is being mishandled and is tuning off
> the tcp_nodelay property (which is by default on) even when set to 'true'.
> amqp://guest:guest@/test?brokerlist='tcp://20.0.10.43?tcp_nodelay=true'
> returns serialised get-put cycles onto a single queue at the rate of 25/sec,
> but
> amqp://guest:guest@/test?brokerlist='tcp://20.0.10.43'
> returns 3017/sec under otherwise identical conditions.
> I assume that the lower performance figure is consistent with tcp_nodelay not
> being active in this test case.
