### Poor ido matching performance on large datasets
Prelude swaps the default `ido` flex matching with the more powerful
[ido-flx](https://github.com/lewang/flx). This might introduce some
performance problems with huge datasets. If you experience lag in
`ido`, please, report an issue upstream. You can always disable the
improved matching algorithm like this:
[ido-flx](https://github.com/lewang/flx).
The sorting algorithm `flx` uses is more complex, but yields better results.
On slower machines, it may be necessary to lower `flx-ido-threshhold` to
ensure a smooth experience.
```lisp
(setq flx-ido-threshhold 1000)
```
You can always disable the improved sorting algorithm all together like this:
```lisp
(flx-ido-mode -1)
