Use this table to quickly ascertain which Relay Server and Outbound Enabler configuration properties you can adjust to tune performance.
| Component | Function | Default | Production Recommendation |
|---|---|---|---|
| Relay Server shared memory | Settings for shared memory buffer. Remember that shared memory must account for concurrent connections, especially with large payloads. | 10MB | 2GB |
| Relay Server response times | To decrease the small payload response time of a Relay Server that is lightly loaded, an administrator can add up_pad_size=0 to the Relay Server configuration file created from SAP Control Center. Adding this value may have adverse affects for a highly loaded server since this setting defeats the built-in network Nagle's algorithm, which delays sending small packets in order to improve overall throughput for many small packets. | None | 0 |
| Outbound Enabler deployment | With SQL Anywhere®, each RSOE provides an upload and download channel to the relay server. | 1 Outbound Enabler per server | 3 Outbound Enablers per synchronization (replication or messaging) port, especially when initial synchronizations are larger than 4MB |
