Hey LaBoot,

I was not saying you are using black hat methods at all. I was saying that there is a way anyone could make the document complete come extremely early by only having 2 resources (1. the main document and 2. an iframe). For a competition bases, it would be better to look at the time it takes for the entire document to load.

It looks like you definitely cut down on the resources a bit. It is a bad comparison because you are comparing FIOS to ADSL. The locations are at least the same for the comparison so thats good.

It takes about 0.4 seconds to know a slight change in load time at least for me unless you are viewing it on slow mode.

I was not discrediting your hard work by any means. I was just trying to give you a few ideas. Also a CDN would make it even faster. Smile

Sincerely,
Travis Walters

For a competition there would be a human element to the judging so the iFrame technique wouldn't work (other than to freak people out on the leaderboards ;-) )

I tried CDN thing (2 companies), and in my case, it is not faster. Things get worse (slower).

One more thing about...

Quote:some black/gray/white/any hat loading attempts

Look at goog -- .ico, .js, and 2 more files are download after Document Complete event.

Google is either evil Huh

or black hat Cool

or creative (speed wise) Idea

Then you weren't using the right cdn. Cdn's are very basic in their concept, and unless you're doing testing locally on your computer and the server is very close to you, a cdn should improve performance by reducing network latency as well as a possible side benefit of increased download parallelization. I'd say if the majority of your visitors are local and your server is local then a cdn won't be of too much use. But if your site is national, or even worse international, then you can really benefit from a cdn.

One thing to be careful with is when testing a CDN make sure to do more than 1 run. The first hit for a given object may be a cache miss on the CDN and they have to go back to the original site to populate the cache. Future requests for the same object should be a lot faster.

How does this site http://www.webpagetest.org/result/100628...811fd1dc9/ get all A's here and in Yslow it scores a 63?

@DJMorrisInc That link does not seem to work.

@Jarichonas Do you have a test URL link?

Oops, sorry....I made the correction up above too, but here is the correct url http://www.webpagetest.org/result/100628...811fd1dc9/

Looking at the page in question, http://www.thaindian.com, I can see YSlow is giving you a lower grade for the following reasons:

This page has 8 external Javascript scripts. Try combining them into one.
This page has 3 external stylesheets. Try combining them into one.
Grade F on Use a Content Delivery Network (CDN)
Grade F on Add Expires headers
Grade B on Reduce DNS lookups

I am getting a score of 83 for your website by the way.

The only real discrepancy I see is the CDN score because the CDN detection algorithm is different between webpagetest and yslow.

Discrepancies in scores are because a different set of criteria and a different weight on each criterion.
