1.) What is the lowest stable achievable latency with
the current stable
(2.4) branch of the kernel (with ll and preempt patches) using Alsa on a
modern system (i.e. at least 1GHz machine)?
total latency: 2.3ms on a dual PII-450MHz, 2.4.19+ll, SCSI, matrox
g400 video adapter, SCHED_FIFO+mlockall required.
2.) What is the lowest stable achievable latency
utilizing
app<--->jack<--->audio hw
kind of setup on a modern system (i.e. at least 1GHz machine) with the
current stable (2.4) branch of the kernel (with ll and preempt patches)
using Alsa?
i can't reliably do better than about 10ms right now on the same setup
as listed above. i am investigating the reasons for this.
