I thought that the change affected the time slicing algorithms and that in addition to helping background services like ASIO, this also helped data transfers by getting a longer slice.

Sorry, but I'm not sure what you mean by "time slicing algorithms". Did you get a chance to look up "MMCSS"?

Again this is blowing dust off my cranium - I thought the number of time sliices - the number of clock cycles - apportioned is made greater for background services - so that they get a bigger slice of the time 'pie', and that a by-product of this was some kind of improvement when doing sustained data transfers, such as the case when doing audio processing.

Again - this is sharing the same memory cells as the disco years for me, so I don't know if any of the above is either correct or coherent.

Ok, I understand where you're coming from now. Here's more info on this subject..., from a very reliable source when dealing with Sonar.

I don't recommend this. Setting the sheduling to background for "better performance" with drivers is a myth. At best this is masking a real problem with the driver. All this does is change the quanta for the timeslice assigned by the windows scheduler. By making the time slice longer you are potentially setting up a scenario where the high priority audio threads in the host application might be denied frequent enough servicing by the scheduler! This might actually result in more dropouts or clicks.

Keni,
 
I think the Macbook Pro has two graphics "cards" one an Intel HD the other an AMD/ATI something-or-other.  I also believe it has the capability to switch graphics card according to usage (although this can be turned off some place in the Mac OS settings, ((If I owned a Mac I could tell you where the setting was))).
It's my theory that the delay may be due to this automatic graphic swithing that the Mac does, as there is obviously low graphic overhead when idle and high when running SONAR.  But I don't know why it wouldn't also happen  with other applications.  In any case, it's a simple user-configurable setting (to turn off automatic graphic switching) which would be quick for you to try (If you can find it).
 
 
 

One of the computers I have has 2 disks, the 2nd a seagate. This computer is set to power-off the screen, disks, monitor, and hibernate. All but the hibernate are set to 15 minutes.

I have noticed the 2nd disk seems to power-off sooner that the C: disk. And the computer is stalled for a moment, when attempting to use it after about 10 minutes.

Some disks have the noise reduction set by default. Could be another bit to check.


I am unfamilier with bootcamp. Does Windows run in a "window?"

Boxed external disks have extra electronics that do the spin-down regardless of the windows power settings.

WOW - we can have the Mythbusters tackle this one!

Thanks for digging that post up - and thanks for explaining,Noel.

I never did fully understand making that change - for the reasons Noel states there - I just went along with it because everybody kept telling me it would protect me from vampires.

Could well be.

I thought I remembered that even though I set the power options to High Performance that if you go into the advanced settings within that power plan that it STILL has it set to turn off the HARD DRIVE after some short number of minutes.

THAT is why I suggest that you go look at that and make sure it is set to some crazy high number - I use 999.

Everything you indicate above points to the hard drive going nighty-nite.

Also, MULTIPLE places on web indicate it is better to have performance optimized for Background Services, so I do not at all understand why you seem to have deliberately not made THAT change - a bit baffling.  Your disk transfer process FASTER with that setting checked.

Anyways, I URGE you to go check that SPECIFIC setting under advanced power settings for the hard drive sleep setting, and likewise urge you to optimize for background services.

Bob Bone

Good Morning Bob and Everyone else...

Wow! What a surprise... We'll see if it helps this morning... I hadn't seen the advanced option beyond setting the two avaialable sleep times to Never.... Now that I did I see the drives were sleeping after 20 minutes which equates (roughly) with what I've been experiencing...

As to Background Services? I see from other posts here that others remembered Noel's comments from long ago... Unless something has changed we were specifically advised/informed not to set it for Background services.... I've had great response with my past systems (within the pc's limitation) and this is the first time I've gad these issues... But as it's also my first Mac/Win7Pro system (personal) I'm learning some more... I'm surprised this hasn't turned up on any clients' systems?

BTW... You might want to change your timeout setting for sleep from 999 to 0 as that sets it to Never!

Much Thanks.... To You and All The Others... I'll post results in a bit...

Keni

Yeah I learned that 0 meant never - just haven't gone back in to change it.  Thanks

So, HOPEFULLY this will take care of your particular problems here, and life will return to its regular stress levels :)

I look forward to hearing how it goes

Thanks Bob... and everyone else too!

It just shows there's never an end to how Microsoft will attempt to fool us for some obscure reason. You'd think that setting them to never meant setting them to never, but then they hide another sleeper beyond it...

I knew to disable the sleep settings, but thought saying Never meant Never! I forgot that it's like saying no to an insistent child! ;-)

The system seems to be responding fine now... We'll see if I missed anything else. Some late morning errands in town and I hope to be back at work before noon!

Thanks again to all for sticking with me and pushing me to learn beyond what I knew!
