Try "sample" on the command line.

Hi list,
I'm making a screensaver (like everybody has done at one time or
another I guess).
My problem is that on 'slower' machines it's taking up to 40%
processor-utilization.
( found by ssh'ing into the machine and using top).
I would like to lower that percentage.
After all, all I'm doing is displaying some text (max about 7 small
lines)
(using: [[NSString stringWithFormat:@"%@",[teksten
objectAtIndex:i]] drawAtPoint:NSMakePoint(x_pos, y_pos[i])
withAttributes:attribuutjes];)
and some small picts
(using: [ster[1] compositeToPoint:NSMakePoint((([self
bounds].size.width - (grootte.height * 5)) / 2) + (i *
grootte.height), y_pos[[teksten count]]) fromRect:NSMakeRect( 0, 0,
grootte.height, grootte.height ) operation:NSCompositeSourceOver];)
and appleevents (querying iTunes (what else....))
I have NO idea where to start, and furthermore: how DOES one analyse a
screensaver while running??
After all, a screensaver (by definitiion) only runs when the user
isn't doing anything.
Does anybody have an idea on how to accomplish this??
Thanks.
Jurjan
