# Tuning

![](/files/-LioWAi8QcOKd6JTp8j5)This category allows you to configure only one setting so far to improve efficiency a little.

**Split users' upload directory** allow you to improve speed a little bit for very high load platforms by splitting the users directories (but this requires a manual operation on disk as well).

Since version 1.8.8.4, you can also find optimisation hints in *chamilo/documentation/optimization.html*.

**Activate the browser sniffer** will scan the users' browsers for specific features.
