Hi Noam,

I think there must be a confusion in the numbers somewhere. Maybe I'm not understanding your numbers. Paul's testing showed his custom-coded solution was running roughly 3 times faster for this use case. This is consistent with your report showing throughput and transaction times on your end. I'm not clear on where the 3.45 comes into play? You don't mean 3.45 seconds per XAware transaction, do you? That would be way too high, and would indicate a configuration issue somewhere. Your report shows about 42 XAware transactions per second, which should equate to about .03 seconds per transaction.

If you are indeed seeing 3.45 seconds, the most likely culprits to look for are 1) a configuration that initializes the engine on every invocation, 2) logging that is set too high (DEBUG level pays a very high penalty and is never appropriate for production... INFO level is recommended).

Also, I see from your report that the XAware test used 1 agent, and the coded solution used 2 agents. Is there some reason for that? If these are client threads making requests, it seems you would want the agent count to be the same for a comparison.

Thanks,

-Kirstan
