Performance differences between libraries, classes and model

[eluser]industrial[/eluser]
Hi,

I am currently creating an math based function that probably will be the most used in the whole application.

Sure, I can go ahead and put it straight into a model as any other database function, but could my server be happier if I put it anywhere else?

If I would make my own library of it, I could call it from inside an view or model as well?

Thanks,

Your server will likely be unhappy no matter what you do. Servers are like that.

If it does nothing other than math stuff - that is, it doesn't do any database access, or more importantly it doesn't require access to the CI superobject, then I'd suggest you stick it in a helper and autoload it.

If it does some database stuff, it might make more sense to turn it into a model (and perhaps autoload it).

If it's a fairly modest lump of code (parsing should be cheap) then you might want to stick it in MY_Controller.
