Back in Ye Olde Days, Gentoo was as cool & popular as Ubuntu is now.  
This is before Ubuntu existed, but when the perception of Debian as  
"boring" (because package versions in stable were so old) was already  
fairly established.

If I look at, say, Slashdot now, I see articles like "Setting Up  
Ubuntu On a PS3 For Emulation", "Jumping To Ubuntu At Work For Non- 
Linux Geeks" and "The Secret Lives of Ubuntu Users" but back before  
2004.0, when the Gentoo installer disks and profiles were called 1.2 &  
1.4, all the generic "using Linux" stories which happened to mention a  
distro by name, mentioned Gentoo. Honestly, Gentoo was in the news  
_all the time_ - that's how I learned about it when I was looking for  
a new distro (when Mandrake went bust for the second or third time).

The most popular distro will naturally have the largest number of over- 
enthusiastic recent Linux converts, and also the largest number of  
idiots. Also your mom. :P

So as you now regularly see blog posts or forum comments or social  
news stories about how "I love Ubuntu because I did this with it" or  
"Ubuntu's loads better than Windows because" - posts which completely  
ignore that the same thing could done just the same with ANY Linux  
distro - we used to see those comments made about Gentoo.

Just as now (a minority of) people will make idiotic claims about  
Ubuntu, back in the day the most common over-enthusiastic claim about  
Gentoo was "it's so |33t - it makes your whole computer faster". A  
couple of posts in this thread have given genuine anecdotes which  
support this, but when the claimant was blatantly an idiot (which  
inevitably was sometimes the case) then one can see how the claim  
might not seem credible to an outside & independent observer.

This is the background which the funroll-loops website satirised -  
"optimised executables" sounds just like it came from that site, and  
EXACTLY the sort of phrase that would've been used by a Gentoo fanboy  
at the time. "Performance" was another favourite word, always used  
blindly or with claims that the GUI felt snappier on Gentoo, rather  
than any actual benchmarks. I'm sure there was at least one amateur  
performance benchmarking article that came out at that time - showing  
Gentoo to be the fastest, of course - and which was immediately  
discredited because the competing distros used safer, more  
conservative defaults (for filesystem settings or something).

To be honest, I am surprised this notion of "optimised executables"  
has stuck around long enough that you've heard it, but it's an old  
joke to many of us who were around in 2004.
