Hi Betty,

Thanks for the response - please note that in the examples I've provided, these
were clean installs of Firefox followed by installing Firebug and YSlow and we
still have the problem.  Also, if you uninstall and re-install Firebug/Yslow,
the problem will come back after several browser restarts.

Please let me know if you are able to find any work arounds - there are several
other people looking into this on the Firebug team as well.

Thanks!
-Darren

I'm interested in finding any historical data on web page download speeds that
goes past the last few years. The data at httparchive.org only goes back a year,
and it apparently has bias. It would be interesting to compare "high
performance" websites today to the resources web pages used 10 years ago - more
or less? My main interest is in how "Jevons' Paradox" might apply to the web -
the hypothesis that increased efficiency leads to a net increase in energy use,
rather than the opposite.

It's a fascinating question.

There are a few data sets that can help here:

Keynote have publicly accessible archives of their benchmark results that go
back a few years.
Archive.org has archived copies of individual pages of many websites.

I was recently looking at (non public) data about performance of an ecommerce
site that's over ten years old. What was striking was that the long term trend
was flat to increasing- response times varied between one and three seconds,
sometimes decreasing for nine months then reverting.

It would be interesting to see a study that considered many sites.

As a performance guy I'm continually struck by the human reluctance to consider
performance data in an objective fashion. Indeed it seems to scare many people.

Hi,

Using PNGSlim <http://graphicsoptimization.com/blog/?p=7> I was able to
shave off a few bytes of the given PNG image.
The original was a PNG24 with 233k and PNGSlim optimized to 217K (16k ~7%
savings) keeping the same quality.
Converting the original to PNG8 (256 colors) using
PNGQuant<http://pornel.net/pngquant>it was reduced to 85K (148k ~64%
savings) but the quality was compromised.
Running PNGSlim on the PNG8 resulted in 78K (155k ~67% savings) the quality
was even worse (faded).

PNGSlim is an awesome tool but it takes longer to optimize, in the example
above took a few hours on PNG24 and around an hour on PNG8.

See attached image results, let me know if one can't get (not sure if Y!
groups will block/discard them)

Best,

Marcel Duran

Rule Don't Scale Images in HTML
<http://developer.yahoo.com/performance/rules.html#no_scale> does not detect the
following cases:

1  Resizing an image with a containing element where the <img> element has no
width and height attributes. For (real-life) example:

<td width="250">
<img height="160" border="0" img="" src="images/may7.jpg">
</td>

2  Resizing images in CSS. Another real-life example:

<img title="Student beside story sack display"
src="/news/PublishingImages/20111214PR1A.jpg" class="image-fixed-width">

Since their omission can give a misleadingly high grade to sites which resize
images in other ways, would it be possible to add these checks to the rule?

Hi Betty,

Has there been any update on this bug?  The Firebug team has offered to assist
in fixing it. http://code.google.com/p/fbug/issues/detail?id=4970 - Please see
comment #9.

Thanks!

Ran into this issue (it's even worse with Firebug 1.9) and put a hacky
fix in since we need it to work properly with GTmetrix.  Here's the
patch we're using:

--- yslow-3.0.4/chrome/content/yslow-firefox.js 2011-08-08

I'm not sure why FBL.extend isn't set up correctly sometimes and I don't
know enough about Firebug internals to fix it properly.  Hope this helps!

Hi,

I'm trying to use YSlow in combination with showslow.
I've got the setup working and yslow is sending data to the beacon in my
showslow instance.

I've set the extensions.yslow.beaconInfo to grade. Accoring to the Yslow 
documentation: http://developer.yahoo.com/yslow/help/beacons.html#yslow_beacon
The data should be sent using a POST request. In my showslow instance I noticed
that most grade data doesn't show up.

Then I noticed, in the apache access logs of my showslow instance, that the data
sent to showslow was sent with a HTTP GET request insead of a HTTP POST.

Did I forget to configure something or is this a bug?

My setup:
Firefox portable 10.0.1 running on window-7(64-bit)
extensions firebug 1.9.1
            yslow 3.0.9

Any help in figuring this out would be appreciated.

Regards,
Marco

Hi people,


I just happened across this group while searching for an answer to a YSlow
problem mentioned at GTMetrix

We're a small part time home based business, and had a guy design us a modest
site, because I didn't even know how to use CSS.

The site is at http://ColoradoProcessServers.net
and is hosted by HostGator for a few bucks a month. :-)

It's edited in Wordpress.

Lately I've been making kind of a challenging minor "hobby" out of tweaking the
speed. The latest was signing up for CloudFlare.

Results at:
http://gtmetrix.com/reports/coloradoprocessservers.net/vvxW9yNZ

On big remaining problem, it seems, is:

Configure entity tags (ETags)
F (0)

40%
	 Server  Low
What does this mean?
There are 11 components with misconfigured ETags

I'm not sure if this is something I can tweak in CloudFlare settings, or not?

At one point I was using the W3TC plugin in Wordpress but it seems to run faster
without it, just trying to do the same things with the Cloudflare settings, only
it caused a different problem with the above.

The site seemed to load faster though, when I used both W3TC and Cloudflare
together. At one point I had it down to about .44 second. Now without the W3TC
it takes longer to load but the scores seem higher, I even got a 100% on the
PageSpeed.

Suggestions on this, please?

Some people think I'm nuts for even messing with this, but it's a little fun and
challenging to me. I'm weird, what can I say? LOL

I want a option to select whether convert gif to png or not,
is it viable?

thx

Multiple background layers CSS3 (2 images on same element) results in 404 error
according to YSlow which is not the case as the page renders successfully in
Internet Explorer, Chromer & Safari, Opera & Firefox.
I guess it's a bug... :-(

Yslow doesn't seem to work with Firefox 9.0.1. I tried it under Chrome and that
works OK. No luck with ff 9.0.1 and Firebug 1.9.0.

Hi
It seems that Smush it removes all of my exif metadata including copyright
information. I thought it would keept that data, as it is stated everywhere,
like in the FAQ...?
So what did I or smush it wrong?

I have two PC's both newly rebuilt Vista (32) & Win7 (64)

Both are running
Firefox 9.1.0
Firebug 1.9.0
YSlow 3.0.4

The YSlow icon is on the status bar with autorun selected and will transfer to
the YSlow homepage - thats it.  There is no tab on the Firebug for YSlow.

I have reset Firebug and set console on and checked the pannels - no YSlow.  
Prior to the rebuilds on the PCs Slow ran on both...

Please advise.
Thanks.
Mark

Dear Vendor,



We are using your software product "YSLOW" in one or more of our engagements at
Travelers in which the software will be used by non-U.S. citizens.  Under U.S.
export regulations, when Travelers provides software access to a non-US citizen,
it is considered an export to that person's home country. It makes no difference
where the software is loaded or where the person accesses the software, when we
provide access, we are performing an export.



The government has a classification system that covers everything from goods and
commodities to software and technology. The classifications are used to define
the government controls and export reporting/licensing requirements.  In most
cases, the government has little or no control/reporting requirements for
run-of-the-mill business software. However, in some cases, this software may
have encryption or certain high performance features that can be used for
criminal or terrorist purposes; these are the ones that they would like to
track.  They do this through the use of Export Compliance Classification Numbers
(ECCN).



The export classification number or ECCN, as it is called, requires in-depth
product knowledge, especially when classifying software products.  As such, we
look to the vendor to provide that information to Travelers.



Please provide the ECCN for "YSLOW" at your earliest convenience.

I just rebuilt (Jan 2012) a Win7 (64 Pro) installed Firefox, Firebug, and
Yslow.
Firebug runs - Yslow icon shows on the status bar but in Firebugs tabs, nor
can I get it to run.  It just transfers to the Yslow home ....

Hi,

YSlow is not working in FF9. Please let me know what need to be done...

I saw a javascript error in the following function

onClickStatusIcon: function () {
         if (typeof FirebugContext !== 'undefined' ||
                 typeof Firebug.currentContext !== 'undefined') {
             Firebug.YSlow.onClickStatusIcon();
             return;
         }


Thanks

I click on the yslow icon and it does nothing. I don't even see a tab in Firebug
for it.

https://groups.google.com/forum/#!topic/firebug/o8B3lAcDI8A

I have installed the Yslow 3.0.4 and Firebug 1.9.0 on Firefox 6.0. But Yslow not
running. Kindly help to me fix the issue.

Woff files should be ignored by the "Compress components with gzip" rule as they
are already zipped:

> The format uses zlib compression (specifically, the compress2
> function), typically resulting in a filesize reduction from TTF
> of over 40%.

- http://en.wikipedia.org/wiki/Web_Open_Font_Format

It would be great if the notice about the missing compression could be removed!

Best,

martin

Etags are generally not needed for static components if you already
have a properly configured Last-Modified and
Expires/Cache-Control(max-age) header.  I'd just ask Cloudflare if
there's any way you can disable the ETags header for your static
assets.

Thanks Phil.

I dug deeper into the GTMetrix explanation and wound up putting

FileETag none

into my .htaccess file, which solved it.

Now, while my scores there are 100/98 the load speed is still around 1 second,
which is odd.

When I had W3TC turned on before, in addition to Cloudflare, it was down to
around .44
second, but the scores weren't as high. So I figured that the Cloudflare
settings were
conflicting with W3TC and shut W3TC off, raising the load time and the scores.
any idea
why?

I figured that running them both would be like running two virus scanners at the
same time,
not only not necessary but possibly conflicting?

I'm afraid this is something you'll have to take up with Cloudflare's
support staff.  I'm not familiar with what they do to accelerate your
website.

hello world

Hi all,
it turns out to be a bug in
yslow.(https://github.com/marcelduran/yslow/issues/5)
<https://github.com/marcelduran/yslow/issues/5> It's already fixed, but
untill it's released the workaround is to set the preference
extensions.yslow.info to the same value as you've set
extensions.yslow.beaconInfo.
Regards,Marco Tolk

If you meant smushit tool, then there's no such option. You can just ignore
those .gif appended with .png, e.g.: image.gif.png
