The difference and applicable scenarios between VLESS Reality and Trojan TLS
Protocol selection should not be based on just one speed test. Stability also depends on line quality, server configuration, client implementation, and current network environment.
Before you start
Operation steps
- 01
Features of Reality
Reality works through a specific handshake design. The server does not necessarily need to configure the traditional public network TLS certificate for the node domain name; the client parameters must strictly match the server.
- 02
Features of Trojan TLS
Trojan usually runs on top of the standard TLS, requires a valid certificate, domain name or matching certificate verification scheme, and the operation and maintenance model is closer to the ordinary HTTPS service.
- 03
Performance cannot be discussed in isolation from the line
The difference between the two on the same line may be smaller than the difference between different operators and nodes in different regions. Continuous testing should be used instead of single delay judgment.
- 04
Faults behave differently
Reality FAQs focus on parameters and handshake targets; Trojan TLS also need to check certificate validity period, domain name resolution and SNI.
- 05
How to use XVPN
XVPN uses VLESS + Reality + Vision as the main protocol, and Trojan + TLS as optional backup; users should give priority to the configuration issued by subscription and do not rewrite key parameters by themselves.
After completion, check like this
- The client supports the corresponding protocol
- Configuration from latest subscription
- No option to manually modify serverName, key or certificate
- Use the same area and the same line when comparing
FAQ
Which one must be faster?
There is no fixed answer. Protocol is only one factor, line congestion, distance, packet loss and equipment performance often have greater impact.
Why does TCP pass but Reality fail?
TCP connection establishment is only the first step, and subsequent protocol handshakes may still fail due to parameter or target exceptions.
