Game Pressure Testing: Execution Steps, Analysis Tools, and Result Evaluation

Pressure testing adds concurrency to game processes (server and client) to observe performance under high load, preventing stalls, crashes, and logical bugs before release.

The full workflow includes four steps: 1) Communicate requirements – planners submit stress test requests based on estimated concurrent users; 2) Clarify the testing plan – define simulation methods, data impact, and behavior patterns; 3) Execute the test – verify load, sample performance, iterate optimization; 4) Write a report – document findings for review.

Typical stress‑test scenarios for MMO games include client‑side tests (new scenes, large resource changes, high‑visibility rendering, large‑group UI) and server‑side tests (new gameplay with >50 participants, whole‑server concurrent actions).

Analysis tools commonly used are:

LuaProfiler – hooks functions to record time and memory before/after execution, producing flame graphs.

Perf – Linux kernel profiling tool for sampling C++ engine code.

VTune – Intel visual performance analyzer for hotspot detection.

ProfilerAnalyzer – client‑side CPU/GPU visualization.

LuaDump – prints table variable sizes to locate memory leaks.

Result analysis categorizes issues into game crashes, memory leaks, unmet performance targets, load imbalance, and high‑load logical errors, each with concrete mitigation strategies and case studies.
