Control transaction dispatch rate:

Browse Source 
Do not dispatch a transaction received from a peer for
processing, if it has already been dispatched within the
past ten seconds.

Increase the number of transaction handlers that can be in
flight in the job queue and decrease the relative cost for
peers to share transaction and ledger data.

Additionally, make better use of resources by adjusting the
number of threads we initialize, by reverting commit
68b8ffdb63.
