The system was nearly unresponsive at 16X (on 2.4.18 SuSE) with my K6-2 400, but I can set it up to 32X now and I have no problems. My recorder never hits 32X with my media though, maxes out at around 20X but I can browse the web while burning with absolutely no fear of my buffer running dry (probably helps that it's a 8MB buffer but cdrecord still never reports it being low).
