HI Folks, Just stepping into RED world. Need some light shed on baking out to ProRes, currently experiencing 20+ times realtime, but have heard of 3 to 4 times. Our path is Redraw to local, into Redcine for a one-lite, then export at ProRes, the settings seem fairly straight forward. Tried 2k,4k 2:1 and 16x9 with same results. These are MacPro, 8 core, 4G ram, Kona 3, Quatro 4500, QT 7.3.1. We're just starting to get acquainted, so what did we miss?

Someone has pointed out that render times were speeded up by setting the preview setting to 1/4 medium before rendering.

3-4 times realtime with a Standard Render (set the display to 1/2 Res High)
15-16 times realtime with a Full Render (set the display to Full Res High)
The key is the display settings depending on the kind of render you're doing.
This is on an 8 core MacPro rendering 4K 2:1 material to 2K ProRes HQ Files.

Have you noticed a quality difference? I'm pretty sure Full comes from the 4K stream and standard is pulled from the 2K stream

Yes, definitely a quality difference.
Standard will reveal sharper and more artifact-y noise patterns (if you're pushing the image a lot in ISO or diving into shadow detail). The noise print is a lot smoother with a Full render.
Also, Standard will show aliasing in areas with super high detail that Full will not.
However, Standard render will appear sharper than a Full render which you can add sharpening to later.
Yes, Standard is taken from the 2K stream (or half of the shooting resolution)... which also means that if you're shooting 3K or 2K, then you have to do a Full render to get full quality - otherwise you'll see jagged edges.
Personally, I like doing Standard renders to ProRes HQ for offlining. Once iBloom announces his full featured 'Crimson' app, conforming the EDL and then doing full renders out to DPX or Kona's uncompressed 10bit RGB 444 codec will be my standard workflow.
