Hi, I use the Openbox window manager with xterm. I just tried replacing xterm with st.
Compared to xterm, st will stutter/freeze when I resize a window by dragging a window edge with the mouse. I have Openbox set to refresh the window contents during the resize. Xterm pretty much stays in sync with my resizing. In comparison, the stutter/lag with st is annoying. If I aggressively resize the window (say 10 seconds of continuous up/down resizing), xterm will stay in sync. st will stutter, then freeze. CPU usage will max out at 100% (mostly in the X server). Even after I stop resizing the window, st will still be frozen (sometimes for over 10 seconds) with CPU usage at 100%. I am running X with the VESA video driver on a 1.2ghz Celeron, on Ubuntu 13.04. I thought the performance delta between xterm and st might be of interest. st also uses slightly more memory than xterm. -Parke
