Can we have some numbers, please? Many people run jackd2 with user privileges, that's actually the recommended way, and none of them experiences a substantial slowdown. So we need to find out what's wrong with your system or particular setup. I suggest a procedure like this: 0. Update to the current package version 1. Stop jackd (killall -9 jackd, if need be) 2. Start top, htop or another CPU 3. Start jackd -d dummy This must not trigger an considerable increase in CPU usage. Then, stop this jackd and start your real jackd. Which parameters do you use? Which soundcard is it? Increasing the buffer size will ease the timing and hence lower the CPU load. Assuming you use ALSA: $ jackd -d alsa -p 2048 --> relaxed timing $ jackd -d alsa -p 128 --> stresses the CPU a bit more In case of firewire audio interfaces, there has been made a fix recently that triggered tons of error messages to be printed on the console, thus making the entire system awfully slow. The newest package has the fix.
