I’m trying to run a Jamulus server . I got it running, but the latency was high. My first step was to add the real time kernel from CCRMA.

CCRMA no longer ships a super-package for core. The main thing missing seems to be the rtirq package.

• installed the ccrma repo file.
• installed the real time Kernel
• Set the RT kernel as the default.
• installed the rtirq scripts rpm
• enabler the systemd module for rtirq
• rebooted
• cloned the Jamulus repo from git
• configure, built, and installed Jamulus from the sources
• added a systemd module for Jamulus
• set selinux to permissive mode (starting Jamulus failed without this)
• started Jamulus
• ensured I could connect to it
• stopped jamulus
• set selinux to enforcing mode
• restarted Jamulus from systemctl
• connected from my desktop to the Jamulus server
• Jammed

It does not seem to have much impact on the latency I am seeing. I think that is bound more by network.
