slow test - nepd - 07-29-2011 10:35 AM

Our website tested pretty poorly.

test result

We have our js ads load after the page... but the load time is still running on them until they complete. Any way of speeding things up with them? Anything else we can do?

Thanks in advance!

There is tons of stuff you can do:

You have 185 (!) Requests on your page. This is HUGE. Try to concatenate CSS and JS files, were possible. Look into the possibility of spriting images.

Especially with JS this is crucial, as it very often has a blocking character, one way or the other. You are downloading 71 (!) JS Files in total.

Your 185 Requests are against 71 (!!!) domains, and most often the only thing that happens, is a Redirect (302, the yellow lines). So you pay the price of a DNS-lookup and a full three way TCP-Handshake (serially), for a couple of bytes. You have 35 (!) Redirects on your page.
Try to get the amount of domains and redirects you are using much much lower.

After that you should look into Caching, as even with a primed Cache you still have more than 70+ Requests. Maybe you want it that way, as this is all Ads, Tracking & Targeting Requests. But IMHO you then should think about, if you haven't gone too far on that end.

Kind regards,
Markus

Thanks Markus-

The tracking and ads are contracted pieces that must remain.

I'm currently running WP - Super Cache, would WP-Minify be something that would help "concatenate CSS and JS files"?

W3 Total Cache would help (and can replace WP Super Cache). It does both caching and concatenating/minifying (some manual configuration required for concatenating)

Thanks Pat... is W3 difficult to setup? Or is it as simple as deactivating Super-Cache and installing W3?

Would Super and WP-Minify get me close to what W3 does?

It's not terribly difficult, you just have to go through a wizard for the minify settings.

Our page test is pretty slow http://www.webpagetest.org/result/110802_4M_17AQW/ as well and i am using w3tc i was wondering if anyone had any ideas on how to decrease the load time. thanks in advance.


RE: slow test - pmeenan - 08-03-2011 06:01 AM

A couple of quick notes (in order of importance):

1 - start with your http page (unless it's common for your users to be using the https version of your page). The ssl negotiation for https is VERY time consuming (4 network round trips). Here is the same page tested over http: http://www.webpagetest.org/result/110802_0X_e75840c62d35467d98cddedbd971ceb1/

2 - Fix all of the 404's. May not help with performance but something on your page is broken (looks like some fancy shadows and whatever tipsy.css is used for)

3 - Go to the minify settings and go through the help wizard to combine your css and javascript files. It looks like you have over 8 css files and over 20 javascript files). Get them down to a manageable number (1-2 of each).

4 - convert those large 24-bit png images to be 8-bit png's: http://www.webpagetest.org/pageimages.php?test=110802_0X_e75840c62d35467d98cddedbd971ceb1&run=1&cached=0 They should look almost identical but they will be significantly smaller.

5 - Take a look at spriting the smaller page graphic images (icons, etc)

I'd bet you can easily get the page under 5 seconds without too much work and probably even better than that.


RE: slow test - dmckinney5 - 08-03-2011 08:13 AM

for w3tc to fully work should i enable mod_expires and mod_headers? and the main reason for the https on the whole site is because of my login boxes located at the bottom of every page i would like my clients to feel secure when using them. thanks for your help


RE: slow test - pmeenan - 08-04-2011 01:45 AM

I think W3TC can operate without the modules but it's probably a good idea to have them enabled anyway (I think it works in a better mode that way - modifying .htaccess instead of routing all requests through the php code).
