Does SecureXL improve non-encrypted traffic throughput and encrypted VPN traffic throughput?

The statement regarding SecureXL's capability to improve traffic throughput is best understood in the context of how these technologies function. SecureXL is specifically designed to accelerate the processing of non-encrypted traffic, leading to enhanced throughput and overall performance. SecureXL utilizes optimizations such as connection multiplexing and streamlined packet processing to make handling non-encrypted traffic more efficient.

When it comes to encrypted VPN traffic, SecureXL does not directly improve the throughput of this traffic. This is due to the nature of encryption; since encrypted data must be decrypted to be inspected or processed by certain security measures, the inherent overhead associated with encryption and decryption processes limits the extent to which performance can be enhanced.

Given these facts, the assertion that SecureXL improves only non-encrypted traffic throughput while maintaining normal performance levels on encrypted traffic is accurate. Therefore, the choice stating that encrypted traffic cannot be inspected captures the essence of how SecureXL interacts with different types of traffic.
