Hi Will, Here you are referring to a wrong properties file. Try this after putting the attached nhttp.properties file to either repository/conf or lib folder of $SYNAPSE_HOME. This synapse.properties file is to tune the synapse thread pool, and it seems you need to tune the transport thread pool which is different from synapse thread pool.
If you run in to any troubles please send us the synapse log so that we can investigate what went wrong...
