The Process Optimizer is a suite of five subsystems that dramatically reduce the RAM and CPU cost of running many Roblox instances simultaneously. Together, they make it possible to run 15–30+ instances on hardware that would otherwise struggle with 5. Enable/disable everything with the master toggle: Settings → Memory & CPU Optimizer → Process Optimizer (Master).

Component Overview

Working Set Trimmer

Drops per-instance RAM from ~450MB to ~70MB by forcing Windows to page out idle memory.

CPU Affinity Manager

Pins each Roblox instance to specific CPU cores via round-robin assignment.

Process Priority Manager

Sets CPU scheduling and I/O priority to keep the OS and Botify responsive.

Crash Handler Killer

Auto-kills RobloxCrashHandler.exe every 30s — saves 15–30MB per instance.

Memory Monitor

Real-time per-instance and system RAM tracking with configurable warning alerts.

​
1. Working Set Trimmer

Forces Windows to page out Roblox’s idle memory to disk — dramatically reducing active RAM per instance. Deferred Mode (trim_only_in_game):
  • Waits ~2 minutes for bots to fully load before the first trim
  • Skips processes younger than 120 seconds to prevent connection timeouts during the join phase
Trim Interval: Runs every trim_interval seconds (default: 120s)
Enable Aggressive Trim when running 20+ instances. Pair with Ultra-Low GPU Mode for maximum RAM savings.

2. CPU Affinity Manager

Distributes Roblox instances across CPU cores using round-robin assignment — preventing multiple instances from competing for the same cores.
  • Core 0 is always reserved for the OS and Botify
  • Each instance is pinned to cores_per_instance cores (1–4, configurable)
  • Assignments are re-verified on each optimizer cycle in case processes respawn
Example — 8-core CPU, 2 cores per instance:

​
3. Process Priority Manager

Sets both CPU scheduling priority and I/O priority for all Roblox processes. Also sets I/O priority to Very Low via NtSetInformationProcess — prevents disk-heavy Roblox asset loading from blocking other processes.

​
4. Crash Handler Killer

RobloxCrashHandler.exe launches automatically with every Roblox instance and serves no purpose for bot accounts.
  • Auto-killed every 30 seconds
  • 15–30 MB saved per instance
  • At 20 instances: saves 300–600 MB total
  • Safe to kill — does not affect gameplay, stability, or connectivity

​
5. Memory Monitor

Tracks system and per-instance memory in real time (updates every 10 seconds): Warning appears in the status bar when system RAM exceeds memory_warn_threshold (default: 85%).
