 One of the improvements in scalability was to move away from a single nodejs process for meteor and have multiple nodejs processes handle the incoming messages from clients.  On BigBlueButton servers, this meant that meteor could use multiple CPU cores for processing messages (each nodejs process runs on a single CPU core).
 
 To enable multiple bbb-html5 nodejs processes, edit `/etc/bigbluebutton/bbb-conf/apply-config.sh` and add `setNumberOfHTML5Processes 2`.  The default is 1; the maximum is 4.
