Has anybody already compared the DSP load/audio real-time performance, when booting linux-lowlatency with and without the "nopti" option?

Done linux-lowlatency/xenial-updates,xenial-security,now 4.4.0.116.122 amd64 [installed] linux-lowlatency/xenial 4.4.0.21.22 amd64 I already booted my Ubuntu install with and without "nopti", but had no time to test performance. Depending on booting with or without "nopti" the command "cat /sys/devices/system/cpu/vulnerabilities/meltdown" either shows "Mitigation: PTI" or "Vulnerable". -- ubuntu-studio-devel mailing list ubuntu-studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
