CPU/GPU CPU usage, or lack there of

[Kannkor]

Back in the day (admittly, years ago now), most of ripping was done by the CPU. Has that changed?

I just moved one of my BD burners into my new computer, and I've done 2 clones, and a full disc rip, and it used about 5% CPU or so.

Where is the bottle neck in ripping movies now a days? I'm guessing a lot was offloaded onto the GPU.

My ripping times seem reasonable, an hour for a full clone. Usually 45 mins maybe an hour for a full disc backup.

Is there any way for dvdfab to utilize more CPU power?

Thoughts?

Unless you are compressing video and a DMA channel is active for the optical drive, the CPU and GPU are not involved, that is the beauty of Direct Memory Access it bypasses the CPU if no data manipulation is required.

Interesting, that would explain it. Previously (well, years ago) I used to compress a lot, now I just dump it onto HDD.

I do have DMA enabled, but if it's not really using the CPU/GPU, what takes so long to rip it to the HDD? There has to be a bottle neck some where... or else it would be nearly instant. I'm sure HDD write speed has something to do with it, but I can copy the file it produces in 4 minutes, rather than an hour.

The read speed of the optical drive is the likely bottleneck. A DVD drive is not nearly as fast as a hard drive.
