Product Performance

Performance Indicators

• Connections Per Second (CPS): The number of new connections established per second, reflecting the ability to handle new connections.
• Maximum Concurrent Connections: The total number of connections per second, reflecting the ability to process connections concurrently.
• Packets Per Second (PPS): The number of packets forwarded per second, reflecting the packet forwarding rate.
• Maximum Throughput: The supported bandwidth.
• Queries Per Second (QPS): The number of queries per second. QPS is not a core indicator, and the one that really consumes performance is CPS. In the case of short connections, QPS=CPS; for long connections, QPS>CPS.

Performance Description

The following performance indicators are the maximum performance that can theoretically be achieved under laboratory conditions. The following are some restrictions and explanations:

• After enabling the ALB log management function, there will be a 10% performance loss.
• The ssl cps is obtained through stress testing under the algorithm conditions of TLSv1.2, ECDHE-RSA-AES256-GCM-SHA384, 2048, 256. For more performance-consuming algorithms, the following performance indicators may not be achieved.
• The ALB instance is deployed in a cluster mode, and the instance also operates in a multi-process mode on a single cluster server. Therefore, for traffic with unbalanced sources, especially traffic from a single source, the maximum performance may not be achieved.
• The maximum concurrent connection number performance of the ALB refers to the sum of the number of connections from the client to the ALB and the number of connections from the ALB to the service node. The monitoring only shows the number of connections from the client to the ALB side.
