Spark is an indispensable utility mod designed to tackle performance bottlenecks within Minecraft environments, whether you are running a client, a dedicated server, or a proxy. It directly addresses the common issues of lag, low tick rates, and excessive CPU or memory usage that can plague players and server administrators alike. By providing deep insights into the game's performance, Spark empowers users to identify the root causes of slowdowns and optimize their Minecraft experience for smoother gameplay and more stable server operations. This mod acts as a crucial diagnostic tool, helping to pinpoint exactly where resources are being consumed inefficiently, thereby resolving frustrating performance problems. This powerful profiler operates by meticulously sampling statistical data about the system's activity, which it then uses to construct a detailed call graph. This graph, a visual representation of function calls and their durations, is presented in an easily interpretable online viewer, allowing for in-depth analysis. Spark offers two distinct profiler engines: the Native AsyncGetCallTrace with perf events, optimized for Linux x86 64 systems, and the Built-in Java ThreadMXBean, an enhancement of the well-known WarmRoast profiler. Beyond CPU profiling, Spark includes comprehensive memory inspection tools, such as heap summaries and full heap dumps, alongside garbage collection monitoring, to diagnose memory leaks and optimize memory allocation. It also provides detailed server health reports, including TPS, tick durations, CPU, memory, and disk usage metrics. spark is designed for broad compatibility across various Minecraft versions and mod loaders. It officially supports Fabric, Forge, NeoForged, and Quilt mod loaders. The supported Minecraft versions include 1.21.8, 1.21.10, 1.21.11, as well as the 26.1, 26.1.1, 26.1.2, and 26.2 versions. Importantly, spark is an optional mod for both the client and the server. This means you can install it on your client to profile your local game, on your server to diagnose server-side issues, or on both simultaneously to gain a complete understanding of your Minecraft environment's performance characteristics. Its flexible installation requirement ensures it can be integrated into a wide range of setups. Installing spark is a straightforward process that requires minimal technical expertise. To get started, simply download the mod's .jar file and place it directly into your Minecraft mods directory. The exact location of this directory depends on the mod loader you are using; for Forge, Fabric, NeoForged, and Quilt, it is typically found within the main Minecraft installation folder. Before launching the game, it is advisable to ensure that your mod loader is up-to-date and compatible with the Minecraft version you intend to play. Additionally, checking the official documentation for any specific setup instructions or known conflicts is recommended to guarantee a smooth installation and optimal performance of the spark profiler.
