Anyway, even if you use the same operating system, kernel version, priority settings, environment, processor, etc. a critical factor is the audio hardware device. Professional or good quality audio interfaces typically allow much smaller buffers, and lower latency as a consequence than cheap/low quality devices. If your laptop has an HDA sound hardware, it is probably the culprit.
Do you know if there are any specific HDA controllers and/or codecs that work better or worse in this regard? I'd be very interesting to know. My experience differs from yours - on my HDA here, I can run with driver=alsa, 4 x 64 buffers quite stable (as in, if there are xruns, I can't hear them). Something I consider OK, especially given the fact that I don't run any special rt kernel (just Ubuntu's standard one, called "generic"), and haven't done the limits.conf stuff either.
