Rob Godfrey commented on QPID-7057:
-----------------------------------
Is the 0-10 client code thinking it can reuse the buffer after it has passed it
to SSLSender.send() ... thus corrupting the output of unencrypted bytes when
buffers go into pending?
> [Java Client] The performance of the client connecting over TLS is
> significantly lower than before

> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: qpid-java-6.1
> Reporter: Alex Rudyy
> Fix For: qpid-java-6.1

> Attachments: SSLSender_experiment.patch, SSLSender_experiment_v2.patch

> The performance tests of current 6.1.x JMS client showed a significant
> degradation of performance with TLS transport (in ~7 times). For example,
> performances of test 'transient_autoack_ssl' with 6.1.x and 6.0.x clients
> using the same cipher suite TLS_ECDHE_RSA_WITH_AES_255_CBC_SHA384 in the same
> environment are as bellow:
> 4241 messages/second with 6.1.x client
> 32455 messages/second with 6.0.x client
