Hi, While doing some CMS development and keeping an eye on the YSlow plugin, i came to think of whether it would be advantageous to, instead of dynamically add...
FWIW, there's already an apache module to combine several files in a single request - http://code.google.com/p/modconcat/. David Artz has a pretty good ...
I think, regardless of the many choices available for how we aggregate files, your question is important. The Right Answer here is arguably an architectural...
There is no hard-and-true solution here— a case-by-case analysis is a better approach. For your specific, CMS, question; I'd ask wether you're talking about...
... Sorry for the hijacking the thread, but is the information sent in the beacon documented anywhere? Some of it I can just figure out, but some isn't so...
I usually look through the WebPagetest <http://www.webpagetest.org> logs daily to get a feel for how the sites people are testing look from an optimization...
I would *love* to see some order-of-magnitude estimates from the smart people who post regularly here. On the subject of CDNs: Mosso has a small-fry CDN for...
Estimates are nice. But they're estimates. I'd like to see some real world before and after measurements from a pool of real life websites. [ Now wondering...
Ryan Doherty had a pretty good step-by step here: http://www.ryandoherty.net/2008/10/12/optimizing-openspacebook/ Initial load time: 12 seconds After reducing...
Yes, I totally agree that too many rules/best practices/etc confuse and overwhelm. I was preparing for a presentation recently[1] and was trying to look at the...
Stoyan/Pat, you guys forgot caching :) Probably the single biggest thing I'm trying to get folks at AOL to do, with the single biggest ROI (on repeat view)....
... thing I'm trying to get folks at AOL to do, with the single biggest ROI (on repeat view). And Pat don't say you covered this in "Reduce HTTP Requests" :P ...
Hi Jonatan, I agree with Eric here "There is no hard-and-true solution here— a case-by-case analysis is a better approach." I work on a big system, where I...
Hi, I was trying to check the possible optimisations on my images via the uploader on http://smush.it/ but in my Firebug console I get this error: 10:30:36...
I agree that those are the heavy hitters. And I think using a CDN is important enough to be included - yes it can hide sins, but for some sites that may be the...
Hey Marin In your browser setting about:config, point the smushitURL to Please point your url to http://www.smushit.com/ysmush.it/ This should fix it pramod ...
I have a small website of 50 pages and I want to call images,js and css from another domain. Like I own abc.com and I want to call this stuff from abc.net. ...
My first Smush-it having tried a small test sampling recently. So I installed Y-Slow and got to work on a simple test site I'm building. 16 images. Alas the...
Hey  The zip file will only contain files which could be optimized. If there are no savings, they will not be part of the zip file. Sorry, I agree it is a...
Hi pramod, I was trying to use the uploader since I'm on a local intranet and I don't find the option in YSLOW2 That's why I tried the http://smush.it website....
It will only boost performance if you are also pulling content from the main site at the same time (so if you move ALL of your js, css and images to the other...
Putting static content on a seperate domain - can certainly help with cookie isolation. If you use cookies for the webpages, then using a seperate domain means...
Cookies don't (or at least shouldn't) factor into caching. If you are serving dynamic content based on a cookie then that content will have the specific...
Thanks Pat for your reply. The plan is to call the js, css from second server while html is loading from first one. I'm unclear of how will it worsen the...
Barry, the website have simple html pages and I don't know much about setting or managing cookies. However, I have asked the developer to put expires header...
You should look at your waterfall and see what can actually be loaded in parallel. Usually the html is downloaded first and then the css and js and then...
That does seem confusing. Maybe the service should return a zip file with two folders: - *src:* containing the files the person sends over - *optimized:...
