for those of you that do require a low latency for your audio routeing, a little known tool called irqballance may help significantly. If i am correct, Fedora Core comes with irqballance daemon pre-installed and I installed it with apt in my debian lenny system, no problem.
For anyone who is wondering, this isn’t the “IRQ ballanceing” option which can be set inside a kernel configuration, that is a deff taboo for low latency. This irqballance is a dameon separate fromt the kernel that helps with irq “prioritizeing”
Okay … I’ve read through… I’m not sure I can see how this will impact latency. Can you explain a strategy to implement on a single socket dual, triple or quad core cpu that reduces latency… How to implement this would be useful too… I get great performance already when using under 40% of DSP (CPU core that is being utilised by Ardour for audio)… but would love to extend this to over 50% if possible…
BTW my studio computer is only on when I am using the studio, powersaving is not a consideration…
