There is a Why ASMLib Fast Facts doc that apparently hasn't yet been put anywhere externally. I checked with the ASM product management team and they're looking into getting that out somewhere so people can see it. For now, I'll send it to you offline - I don't think we're allowed attachments on this list. Anyone else who wants it let me know and I can send it to you as well.

I also couldn't find any info on why would I want to use ASMLib instead of standard Linux raw-devices. If anyone has some facts and/or documents, please share with us.
So far I only found Jared's comment in "Adventures in ASM" article: "Some preliminary testing (admittedly, on a single machine so far) indicates that the of ASMLib I/O may cost a significant I/O penalty. You will need to test this on your own system to determine if this is so for you."
