Memory Usage Test

Test 1

What Was Tested

soga's memory-optimized data structures for VMess MD5 authentication info

Test Description

VMess MD5+VMessAEAD authentication, multiple users, all with alterId 0

Test Environment

Ubuntu 20.04, 4 cores, 8 GB RAM, no swap

Test Method

Add 10000 users, leave the program idle for 10 minutes after startup, then measure memory usage

Test Data

Program	Memory Usage	Memory Percentage (lowest value of the original = 100%)
soga(v2.5.3), default configuration	193MB	46%
soga(v2.5.3), with v2ray_reduce_memory=true	118MB	28%
v2ray(v4.41.1)	424MB	100%

Test 2

What Was Tested

Simulates real-world user traffic to test soga's memory optimization under a large number of connections

Test Description

VMess+MD5+VMessAEAD authentication, websocket transport, 1 user, alterId 0

Test Environment

Ubuntu 20.04, 4 cores, 8 GB RAM, no swap

Test Method

Client->Proxy program->Server (simulated website)

1. The client opens multiple connections to the server through the proxy. On each connection, the client sends a random 4KB~16KB packet to the server every second, and the server sends a random 4KB~16KB packet to the client every second
2. Each connection stays open for a random 30~120 seconds and then closes; a new connection is opened immediately after each one closes, keeping the total number of active connections constant
3. After running for 10 minutes, memory usage levels off; memory usage is measured at that point

Program	Memory Usage (1000 connections)	Memory Percentage (lowest value of the original = 100%)
soga(v2.5.3), default 16KB connection buffer	179MB	55%
v2ray(v4.41.1), default configuration	1203MB	368%
v2ray(v4.41.1), 16KB connection buffer	380MB	116%
v2ray(v4.41.1), connection buffer disabled	327MB	100%
xray(v1.4.2), 16KB connection buffer	416MB	127%
xray(v1.4.2), connection buffer disabled	391MB	120%
