spark is a performance profiler for Minecraft clients, servers, and proxies, combining a lightweight CPU profiler, memory inspection tools (heap summaries, heap dumps, GC monitoring), and server health reporting. Results are uploaded to an online viewer for analysis, and it installs as a plugin or mod on platforms like Bukkit/Spigot/Paper, Fabric, Forge, BungeeCord, and Velocity.

Use cases

• diagnose lag and low TPS on my Minecraft server
• profile CPU usage to find performance bottlenecks
• take a heap dump to investigate memory leaks
• monitor garbage collection activity on a Minecraft server
• track server health metrics like TPS and MSPT over time
• profile memory allocations causing server hangs
• find which plugin or mod is causing tick lag

When to choose

• you run a Minecraft server, client, or proxy and need production-safe profiling with minimal impact
• you want quick, no-setup diagnostics of lag, CPU, or memory issues
• you need readable call graphs and shareable online profile results

When to avoid

• you need deep JVM profiling beyond Minecraft workloads - use async-profiler or a full APM tool directly
• you need a general-purpose application performance monitoring solution for non-Minecraft Java services
• you require profiling on platforms unsupported by the native async engine (though the Java engine still works)
