… sounds cool.
We just have our nodes running with 20-50% of ( one) CPU-usage.
And another story, with 98% showing lines ala:

May  4 21:06:57 fcmsnode10 ovs-vswitchd: 3827527|poll_loop|WARN|Dropped 635 log messages in last 1 seconds (most recently, 1 seconds ago) due to excessive rate

in the syslog with 1.4.0 ever so often. Dunno yet, what's going on…
