I have a DVDR with 3.5Gb on it, I want everything that is on there on my Powermac G4 digital audio's HD. It's copying but I get a speed between 300kb and 1.2Mb ... isn't that very slow ?

I've encountered similar speeds when copying a large number of small files on my Mac Mini 1.42Ghz machine.

I've noticed the MorphOS file copy speeds are much, much slower than MacOS Leopard running on the same hardware. In some cases, around half the speed. I would also be interested in any solution.

Are the DVD and hard drive both on the same ATA cable? That would slow down copy time significantly compared to using seperate ATA interfaces.
AFAIK both the mac-mini and Powerbook only have a single ATA interface, which impacts performance in certain cases (such as copying optical>HDD) considerably, especially if the optical drive starts dying.

Simply open a shell and enter the following line:

AddBuffers cd0: 20000

Afterwards copy should be faster. (In fact you can change buffers even during a slow copy to speed it up) Same is done internally when booting from CD-Drive. It makes no sense to increase buffers as each buffer is 2K. It is not done by default as most users do not need the CDROM at all. You can add the line to your user-startup adding >NIL: of course.

Bigger values are of course possible, too, but you may not experience any speedup. Same works for HDD and USB drives.

Unlike the CD/DVD-ROM you can change default values using HDConfig,too. By default they are set to 64. For HDD I recomment 4096.
