Throttling the player's ability to fire remotes rather than an instant crash, which can be less intensive on the server.
Use this to visually see unoptimized portions of the game loop that might cause "stuttering" or "lag-crashes". 4. Automated Instance Management

Server-side examples (Roblox Lua)
Roblox is a popular online platform that allows users to create and play games. However, with the vast array of user-generated content, crashes can occur, disrupting the gaming experience. To mitigate this issue, developers use anti-crash scripts to prevent their games from crashing. In this write-up, we'll explore how to create a better anti-crash script for Roblox.
Searching for an is a common pursuit for players and developers who want a smoother experience. Whether you're a developer trying to protect your server from malicious exploiters or a player tired of client-side freezes, finding the right "better" script requires understanding how Roblox handles stability and security. 1.
