Don is right. The AOLserver installation guide (that I wrote) is wrong. When I wrote that nsd8x was a new thing in AOLserver and it was slower, but progress has been made, which is great. I overlooked that when I made the 3.2.4 release of the docs. It will be corrected for 3.2.5.
Thanks for pointing that out. If you'd be so kind as to post that as a bug in the SDM for the documentation, I'd appreciate it.
