This is about the interactive feel of the desktop, like clicking, dragging, and rendering operations. JWM seems more instantaneous and direct. Am I missing the JWM Desk settings?
I'm thinking LXDE & XFCE.
I've been appreciating LXDE lately as those peebee distros switch to JWM well.
Trying to run XFCE from the PPM demands a lot of customization, and the puplets either exclude or butcher JWM (e.g., no pinboard).
Otherwise I've been trying to recognize how they use ram. There's something more going on beyond the memory usage at boot.
