While waiting for the 1.2 final release..

["Asankha C. Perera" <as...@wso2.com>]

Hi all

While waiting for the Synapse 1.2 release to be final (i.e. the WSS4J 
and Rampart release votes to close), I am conducting some load and 
performance tests against the codebase.

So far I have found and fixed one issue that resulted in an error for 
about 300,000 ~ 400,000 1K requests and responses with 80 concurrent 
users and consistent load. I will conduct further tests with larger 
messages around 5K and 10K. I will commit this fix soon with a 
corresponding JIRA after I complete my tests. I have also load tested 
against the 500K request raised in SYNAPSE-287 again, and now we use 
constant memory without errors.

Recently we also found out that we are now safe from a bug that could 
put Synapse 1.1.1 into an endless loop when using outgoing SSL 
connections (http://www.nabble.com/ESB-uses-100--of-CPU-td15977377.html)

I strongly suggest that any users run any performance test scenarios 
with the last build, and to let us know if you suspect any issues
