From Observer GigaFlow Support | VIAVI Solutions Inc.

Performance Changes

- Changed order of performance graphs; now interfaces launch after devices.
- Improved zmq memory usage by approximately 15%.
- Changed drop handling for syslog messages; rather than drop the buffer, it no longer admits to it.

Fixed Issues
