[LAU] getting better performance on arch/kernel 3.3.4

Hi This has been bothering me for a while, and trying to catch up on the rtirq thread, I thought I'd ask here: I'm running arch, and I used to be quite happy with the performance with the stock arch kernel. But something happened around 3.1 (or so). Now I get xruns every once in a while, even with conservative buffer settings. It used to work just fine with both alsa and through jack, and now the problem is both places, which leads me to believe that's it's got nothing to do with my jack settings (but I might be wrong). Before I cat my whole box here, maybe someone had a similar experience and knows a solution. Or could extract the conclusion from the rtirq thread, the information in there seems overwhelming. -- Atte http://atte.dk http://modlys.dk
