  Could someone explain what the values mean? I mean, I
imagine Memlock
 means max memory allocate, but to what? I have 1.2 gigs of ram and I
 can spare more thatn 512megs... Also, I<ve heard of people using
 different nice values... What does this do?

 Thanks

  I order to use my audio applications (related to
latency) more efficiently,
 I gave some priorities to the applications which are in the "audio" group by
 adding the lines below, to the file "/etc/security/limits.conf"

 @audio - rtprio 95
 @audio - memlock 512000
 @audio - nice -19

 By doing this, to which application did I give the priority ? 

 To a *user* belonging to this group. Just add your user to group audio and
  re-login to your desktop.

 Alsa, Jack ... ?

 How is that defined in GNU/Linux ?

 I mean,
 Did I give this priority to all applications using the sound device or to
 the applications that are included in the "audio" group ?

 Who, what or which are in the "audio" group ?

 Thanks.
