I have been using Arch Linux+XFCE since around 2010. My previous personal PC was 10 year old Pentium 4 and with the fastest (SATA) SSD the machine could support, and everyday usage felt faster than many modern peers at the time. OTOH, I always wondered how big difference would it have with LXDE, IceWM, MATE or Enlightenment instead.
