RAM consumption is the same as LxLE, but more efficient and because of Whisker Menu and other tweaks that let us feel more like we have a XFCE desktop environment, as keyboard shortcuts, for instance, it looks like we got here the fastest and lightest, globally speaking. Very good on performance. Download Respin 7 (March 2017), install Libreoffice and then compare, for example, opening Libreoffice Writer inside Peppermint 7, Extix 17.04, Lubuntu 16.10, Xubuntu 16.04, Backbox 4.7, Linux Mint 18.1 Xfce an Mate or Linux Lite 3.4 (and others). Finally, you'll find out that after opening a few apps in Peppermint it remains smooth and light. Nemo file explorer on Peppermint is incredibly faster than on Mint Cinnamon; lx terminal is very fast when opening; updating is fast. And after all this, distro keeps working and working very solidly and consistently along the time. And yet the look and feel of the environment is pleasant.

The XFCE Whisker menus and dark theme are well designed.
Easy to move the panel to the top and add plank on the bottom.

There are enough useful back end packages installed by default to make the system useable for normal use right after the installation of the base distro.

Works great with Teamviewer, Synaptic, XNview, KODI, and Pdf-Xchange editor (via playonlinux). Netflix works awesome with Chrome browser. The ICE SSB tool is great for creating web apps that run as if you installed them locally.

The Software Boutique (packaged with The MATE Welcome software Center) recognizes all software and installs it with one click.
