     "# Optimising _Cheetah_ for speed\n",
     "\n",
     "One of Cheetah's standout features is its computational speed. This is achieved through some optimisations under the hood, which the user never needs to worry about. Often, however, there further optimisations that can be made when knowledge on how the model will be used is available.\n",
-    "For example, in many cases, one might load a large lattice of an entire facility that has thousands of elements, but then only ever changes a handful of these elements for the experiments at hand. For this case, Cheetah offers some opt-in optimisation features that can help speed up simulations significantly by an order of magnitude or more in some cases.\n"

As this notebook demonstrates, speed improvements of more than 5 orders of magnitude can be achieved.\n"
