Because Neurona@Home only provides a WU each time, and many hosts wait some time since the task ends until they report the result and get a new one, the processing rate may be low.

Dagorath (thanks) has given us an interesting advice that you may try:

Volunteers can force completed tasks to report immediately by using the report_results_immediately option in a cc_config.xml file in the BOINC data directory.

<cc_config>
<options>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

This will also cause hosts to get another task immediately. This should increase Neurona's work rate if hosts are waiting many minutes to download another task.
