Hi Linux (and some other Linux distroes) users of lmms,
If you - like me - use lmms on a not so top-of-the-line box and hit lags, delays, excessive CPU consumption or some sort of trouble related to system resources when playing music, I found a useful resource there: http://wiki.linuxaudio.org/wiki/system_configuration
It gives a lot of tricks for you to try to make things run smoother.
There is also an interesting diagnosis tool there: https://github.com/raboof/realtimeconfigquickscan
It is a bit abandoned but, the perl script analyses your Linux kernel settings ans suggest changes (even giving links for more information) to improve performances for music making, even without a real-time kernel. But be prepared to google to go further
I used both resources to tune up my box, a P4 2.8GHz with 2 Gb of memory running Ubuntu 12.04 LTS (no realtime kernel) and all the problems related to resources were solved without even changing the lmms settings related to performance.
If this can help at least one lmms user, I will be happy
