Rob, I've had a chance to review the latest updates to QPid. And while the memory leak has been lessened it has not been removed (to be expected I think). However, on the downsie, the performance of the AMQP 1.0 code seems to have declined significantly. I'm attaching the results from 2 performance tests. In each a single consumer and single producer is communicating with the QPid-J broker, using messages of roughly 1KB in size. (I say roughly because it is a timestamp plus garbage data). The 2 brokers compared were Qpid-J v0.20 and the latest pull from the GIT repository. Both tests were stopped after the host system (in this case Macbook Pro, Intel Core i7, 64bit, 4 core, 8 GB ram) reported (via top) that the JVM had consumed resident private address space exceeding 900 MB with an mx of 1024.
The attachments show the number of messages sent and recieved per second, followed by the latency of the messages. Where I'm concerned is in the throughput - QPid 0.20 demonstrates an AMQP 1.0 throughput n the order of 12K messages per second but with a large leak into ram. Your recent work into optimizing the 1.0 Java code has significantly reduced this, allowing the tests to run for longer, however the performance is greatly reduced to about 2000 messages per second. Looking at VisualVM on OSX (I'm new to VisualVM), in the profiler for the QPid proces, shows that the largest class allocation in the QPid proces, in both cases, is of type 'byte[]'. Not having dug into the code yet I'm not sure what necessarily this means or even if its of any help. However I'm attaching my test results in addition. I'll also say that while I've gotten similar results using both client code bases, the tests attached to this email were collected using the SwiftMQ Java client library.
