Yep, with a resolution of 320x240 composite should not be a performance
problem, more likely a memory problem as every X-window will have a
offscreen buffer and devices with such screen don't tend to have much
memory in them. What kind of device are you using?

You might want to try using Matchbox's composite engine (you can enable
it via configuration options) or try xcompmgr  from freedesktop.org
which is a 'minimalistic' composite manager.
