[linux-audio-user] regarding services and cron jobs

[Dave Phillips]

Greetings:

  I've tacked on a copy of top's report for a plain-vanilla Planet CCRMA 
RH 9. I'm going to be advising a client regarding what services he 
can/should disable for best-case recording (with a nearly identical 
system), so I thought I'd use my own system for the primary tests. I'd 
like to know which of the services and jobs listed by top can be safely 
disabled during the use of a setup consisting of Jack, Rosegarden, and 
Hydrogen, all in the latest & greatest versions from Planet C. Any and 
all suggestions will be cosmically appreciated.

  Btw, at the time of the screen capture I was running Jack (qjackctl), 
Mozilla, XMMS, and FileRunner, a Tk-based file manager (which is why you 
see a wish instance in the top report). This report was generated for my 
desktop machine.

Best regards,

dp
