# Network Enhancement Performance Data
**Note: This document only provides benchmark performance tests, which measure the maximum performance values achieved via the UDP protocol with small/large packets. The actual packet volume in specific business scenarios is affected by multiple factors such as upper-layer applications and communication protocols. Please refer to the results of real-world business load testing.**
## Network Performance Test Indicators
**Packet Volume** (common units: pps): The number of network packets processed per second. This is the core metric improved by network enhancement features.
**Bandwidth** (common units: mb/s): Network bandwidth refers to the maximum amount of bit data that can be transmitted within a fixed time (1 second).
**TCP_RR** (common unit: times/second): Tests the response efficiency of multiple TCP requests and responses in the same TCP connection. This scenario is commonly found in database applications.
**TCP_CRR** (common unit: times/second): Tests the response efficiency of requests and responses across multiple TCP connections, where each TCP request/response establishes a new TCP connection. The most typical application is HTTP web access requests, where each request/response occurs in a separate TCP connection.
## Test Data
### Test Environment
**Test machine:**
Image: CentOS 7.2 64-bit
Specifications: 1) 8-core CPU 16G memory 2) 16-core CPU 32G memory
**Auxiliary machine:**
Image: CentOS 7.2 64-bit
Specifications: 8-core CPU 16G memory * 8 units
### Test 1. Packet Rate test
Using UDP_STREAM, small packet (1byte) test.
**Conclusion**
* Network enhancement can significantly increase Packet Rate. Under the UDP test, the peak packet processing ability can reach over 1 million pps, which is 3 times that of the case without network enhancement.
* The packet volume capacity of SCloud is irrelevant to the size of the specification.
### Test 2. Bandwidth test
Using UDP_STREAM, large packet (1400bytes) test.
**Conclusion**：Network enhancement can significantly increase bandwidth, but in the outbound test, it has reached the maximum bandwidth bottleneck (10G) of the internal network, so it can't increase further.
### Test 3. TCP_RR and TCP_CRR test
Since the round-trip path remains unchanged, a single link can only utilize one core and one channel. Therefore, enabling network enhancement does not make a significant difference, and thus cannot significantly improve TCP_RR and TCP_CRR.
