Page speed - huge diff between chrome ext and ps website

[cmendla]

I was checking a site with Google Page Speed.

When I looked at the score based on the results from the Google extension, I got a 71/100

When I evaluated the same site via the Google Page Speed site, the score was something like 51/100.

That seems like a huge difference.

I checked another site (with less traffic) and it was 71 on Page Speed's site and 81 on the chrome extension.

I'm trying to benchmark a site prior to making some changes and am trying to figure out why there is such a difference.


thanks

Which extension did you use? FF or Chrome? I get different from both and they claim that compression isn't on certain files when it is. The PS site shows 100 (which is what outside scores are) but the browser tools show the same pages at 91 to 93. My cases are the opposite of what you see, the browser plugins are inaccurate.

There are sites that give a more detailed picture rather than a single number.

Try gtmetrix DOT com and pay attention to the waterfall reporting. It's not just the html....it could be the db loading.

I've found that social plug ins that use remotely served scripts and buttons are all over the place d/l time-wise depending on the hour of the day.

Str82u - I was using Chrome. I appreciate the input on the plugins.


Hoople - Thanks - I've been learning about the waterfall displays over the last couple of months. I'm glad you mentioned the social plug ins. I had one a while back that was really slowing the site down. I'll revisit that are.

Thanks

Try gtmetrix DOT com and pay attention to the waterfall reporting.

We normally don't discuss specific tools here to avoid self promotion, but I'm making an exception for this discussion. Gtmetrix is already mentioned in our Favorite SEO Tools thread [webmasterworld.com]. It's been one of my go-to tools for a few years. I agree that it is excellent, especially the waterfall breakdown for every page element.

i wouldn't worry about the numbers and instead address all the specific issues under your control.
if you use gtmetrix, it will list every issue found by google page speed and yahoo yslow.
in some cases, you can't do anything about a reported issue for a resource.
for example if you have some external javascript on your page that is hosted elsewhere, you can't do much about minifying it or compressing it or providing the proper headers for caching it.
