Half as fast, but still faster
Just updated my old dual 2.7 G5 with a 8-core 2.8 with 16GB of RAM with a RocketRAID card 2314 running RAID 50 with an 8TB Burlybox.
My question is speed. It’s a lot faster than what I had, but I’ve noticed that when I render in FCP or in Compressor (or even both at the same time) Activity monitor tells me that the processors are only under half load–400ish–and the “LED” meters show the same thing.
I’m guessing Apple just hasn’t optimized their software to fully take advantage of 8 cores, because I can start a render in AfterEffects CS3 and Activity Monitor shows the pedal to the metal on all 8 cores.
I’ve poked around for ways to optimize FCP and Compressor, like you can in AE, but haven’t found anything.
Am I missing something?

[David Hames] “Am I missing something?”
Nope.

At least we’ll soon be able to play cool games on our iPhones–Oh, wait, I don’t have an iPhone. But waiting for Apple’s latest “workstations” to finish a render is a great excuse to buy one!!!
This is the kind of stuff that feeds the rumors that Apple is abandoning Pro Apps.

Sorry, I should add that you can setup a virtual cluster in Compressor to make for faster compressions.

Are you running Tiger or Leopard?

Running Leopard. Is Tiger optimized? That would be ironic.

Could you explain or point me on how to do that (create a virtual cluster)? The manual doesn’t have anything on virtual clusters, just clusters. Are they the same thing? Or are you talking about setting things up so that Compressor thinks each processor on my 8-core is a separate computer?
I saw some command line instructions in the manual regarding clusters, but the bulk of it was a bit over my head. If it will cut renders in half I’ll learn it, otherwise I’ll probably have to wait until an upgrade provides a check box “for the rest of us.”

I’ve got 8-cores pegged in activity monitor–it’s a beautiful thing.
Thanks so much for your insight.

I thought it was the other way around.
