People cannot detect the difference between 1000usec and 50usec
latencies, so they aren't going to notice any changes in
responsiveness at all.
Excuse me?
You are excused ;)
1 second (1000 usecs, 200 times your 50 usec example) is
1000usecs is 1msec.
VERY noticeable when you are listening to music, or worse yet, trying
to edit it. For much of that, submillisecond accuracy makes or
breaks the application.
For listening to music, 1msec is absolutely no problem. For editing,
perhaps it is getting problematic. But Andrew (and parent) were
not talking about realtime applications, but *interactivity*.
Lets get out of the server only camp here folks, linux is used for a
hell of a lot more than a home for apache.
Let's all try to keep calm and think carefully about what someone has said
and in what context before responding.
This is a topic that for some reason will tend to degenerate into a random
shouting match where nobody actually says anything or listens to anything,
and nothing gets done. Not to say you are trying to start a flamewar, Gene,
but everyone just needs to tread a bit carefully :)
