+.IP \(bu
+Approximately 256 bridges given the allowance of 5,000 file
+descriptors that \fBovs\-ctl\fR(8) configures.  (\fBovs\-vswitchd\fR

+Kernel flows are limited only by memory available to the kernel.
+Performance will degrade beyond 1,048,576 kernel flows per bridge with
+a 32-bit kernel, beyond 262,144 with a 64-bit kernel.

+OpenFlow flows are limited only by available memory.  Performance is
+linear in the number of unique wildcard patterns.  That is, an
+OpenFlow table that contains many flows that all match on the same
