Ooopppss...
Forgot to give more background info. Basically, Mozilla supports
Pipelining and it seems to give a noticeable performance boost (theoretical max is supposedly up to 10x faster).
It seems IIS doesn't (http://www.pipeboost.com/default.asp), and Apache does (http://httpd.apache.org/docs/misc/FAQ.html#what).
Can't seem to find any info on the Aolserver.com page (no more search!) that's why I'm asking here.
