 After adjusting your system using the recommendations of [[system_configuration#rtcqs]] and with JACK (QjackCtl) and a2jmidid installed, the basics should be there for a well performing real-time audio system (depending on your hardware too of course). After adjusting your system using the recommendations of [[system_configuration#rtcqs]] and with JACK (QjackCtl) and a2jmidid installed, the basics should be there for a well performing real-time audio system (depending on your hardware too of course).

 To work around the Spectre and Meltdown vulnerabilities several mitigations were built into the kernel. These mitigations can have a negative impact on the performance of your machine. To disable those mitigations and get the most out of your CPU's again you can add the following kernel parameter to your Grub configuration, add it to the value of either ''GRUB_CMDLINE_LINUX_DEFAULT'' or  ''GRUB_CMDLINE_LINUX'': To work around the Spectre and Meltdown vulnerabilities several mitigations were built into the kernel.

 With the help of ''top'' you can find out which process is using up all your CPU or memory. By pressing ''h'' you get a help screen. To sort on memory usage instead of CPU usage you can press ''F'' + ''n'' + ''Enter''. With the help of ''top'' you can find out which process is using up all your CPU or memory.
