Why is my Sim so laggy ?

So lets start with what a sim is:

Second Life's Definition of a Sim

Simulator, which can mean either:

• Sim node (or sim host), the physical server machine simulating one or more regions.
• Sim processes, the processes running on the server machines that simulate regions.

The latter usage is more precise, because multiple processes may run on a single server CPU. In common usage, "sim" may also be used to mean region, though this meaning is deprecated because it is ambiguous. Most accurately, a region is simulated by a sim process running on a sim node.

• Sim means sim host, or the hardware
• Simulator is the binary that runs on the sim hosts
• Regions run in the simulator .

so the first place to look if your Sim is laggy is here:

Why is my sim Laggy?

• Whats that all about ?

Common usage of the word sim normally means the whole island or region and the numbers you see on this page are an indication of how busy they are.

• FPS should be 44 or more, Dilation should be 1 or less.

You will notice if FPS goes below 42 and if it goes below 30 then you will start to suffer, Ive been in a sim thats been running at 22 FPS and that was not  a good experience.

• There is only me on the island and its still laggy.. help !!!!

Lots of reasons for this if your land has loads of scripts running on it then it will slow down badly ... the main issues that cause this are Clubs and events.


 Some clubs run massive lighting systems that can bog down a sim without there being anyone there.
and some clubs encourage bling and lots of funky clothing.
