About this product
DayZ Server Performance Profiler & Engine Diagnostics Tool
Stop guessing why your DayZ server is lagging, stuttering, or dropping FPS.
Most server administrators rely on generic task managers or basic resource monitors that only report total CPU and RAM usage. While helpful for basic server health, those tools leave you completely in the dark when performance degrades: Which mod is causing the lag spike? Which specific script or function call is stalling the server thread? Is it a disk bottleneck or an unoptimized RPC network event?
The DayZ Server Performance Profiler is a 100% standalone diagnostic and performance profiling suite engineered specifically for DayZ server owners, hosting providers, and mod developers. By hooking directly into the server engine level, it gives you unrivaled, real-time insights into every microsecond of execution.
Key Features & Deep Diagnostics
1. Direct Engine & Script Call Profiling
Function-Level Execution Tracking: Inspect the precise script function calls executing in real time.
Exact Line-of-Code Identification: Pinpoint the exact line of code in any Enforce Script (.c) or mod file that is taking too long to execute or throwing execution bottlenecks.
Tick Rate & Frame Time Breakdown: Analyze server frame times down to the millisecond to eliminate low-FPS spikes.
2. Per-Mod Resource & Performance Attribution
Per-Mod Impact Metrics: See the exact percentage of CPU time and server frame delay consumed by each individual mod.
Isolate Problematic Mods Instantly: Identify heavy, unoptimized, or leaking mods immediately after installation without tedious process-of-elimination server restarts.
3. Advanced Memory & RAM Analytics
Granular RAM Usage: Track total physical memory, commit charge, and garbage collection behavior.
Memory Leak Detection: Track heap allocation trends over time to identify slow memory leaks caused by poorly written script loops or unmanaged entities.
4. Disk I/O & Storage Performance
Read/Write Throughput Monitoring: Track real-time disk read/write operations (MB/s) and I/O latency generated by server saves, database persistence operations, and custom file logs.
Storage Bottleneck Alerts: Instantly detect when slow storage (HDDs or congested NVMe drives) is causing global server freezes during world writes.
5. Network Traffic & RPC Analysis
Inbound/Outbound Bandwidth: Monitor real-time network payload bandwidth and packet rates.
RPC & Packet Load Tracking: Identify spammy client-to-server or server-to-client Remote Procedure Calls (RPCs) and sync requests before they choke your network throughput.
