Code Optimization

Optimize your code for better server performance. Measure each change with resmon under representative player load before treating it as an optimization, and compare results against a repeatable baseline.

Avoid while(true) Loops

Bad


while true do
    Wait(0)
    -- Do something every frame
end

Good


CreateThread(function()
    while true do
        Wait(1000) -- Wait 1 second
        -- Do something
    end
end)

Throttling

Prevent excessive function calls:


local lastCall = 0
function throttledAction()
    local currentTime = GetGameTimer()
    if currentTime - lastCall < 1000 then
        return
    end
    lastCall = currentTime
    -- Do action
end

Caching Natives

Cache expensive native calls:


-- Bad: Called every frame
local coords = GetEntityCoords(PlayerPedId())
 
-- Good: Cache and update periodically
local cachedCoords = vector3(0, 0, 0)
CreateThread(function()
    while true do
        Wait(100)
        cachedCoords = GetEntityCoords(PlayerPedId())
    end
end)

Best Practices

Use appropriate Wait() times
Cache expensive operations
Throttle frequent calls
Profile your code
