We use kst for realtime plotting over long periods of time quite successfully. (Multi-channel, multi-KHz, multi-day)
We have some beefy machines but I don't remember seeing "significant" CPU or memory consumption by kst.
Some tips: don't use points on your plots and change the range and/or subsampling.
