as of 20:00 tonight wowhead.com is lagging out the forums again making them all but unusable.

I have added http://www.wowhead.com/* to adblock plus for FF but that doesn't help in Chrome obviously

Not seeing any lag here.  Browsing forums is quick and simple atm, certainly nothing even vaguely approaching unusable.  Wonder if it could be anything else?  Using FF here.

I've disabled the plugin temporarily as there is a new WoW patch out tomorrow and everyone is busy checking the various info sites (wowhead being one of the major ones). As a result these sites are slowing up a bit under the pressure and as a consequence it affects us.

I'll re-enable the plugin in a few days when wowhead recovers :)

Leave Snooks out of it.  He's just old.

But back to Wowhead.  Seriously, I am flying through the forums and wondering what the heck people are on about.  I hardly even see wowhead at the bottom of a page load, let alone on eveyr page and certainly not 20-30 second loads.  So why are we seeing such different performance?

Im noticing any delay at all when browsing the forums, could it be some routing issues from wowhead to certain members ?

My guess would be that it might be random which site (among the different scripts that run on this forum) you see as "waiting for..." in the status bar. Just now while browsing this thread, I notices that "waiting for www.google-analytics.com" was there for about 10-15 seconds. It didn't seem to slow down the loading/my reading of this thread, so even though you see it doesn't necessarily mean it causes any problems.

And for those that see it as a problem: with an addon such as adblock or no-script, you can just put wowhead on your blacklist and you'll never see it again (of course that won't be a viable solution for those of you that actually do find the functionality it offers useful).

I use No-Script and wowhead is an allowed script, but I still see no delays.  I have google-analytics blocked on deadmen, everything else is allowed.

Now it's OK, I still get the 'waiting for wowhead' but it's only about 1/2 second, if that.
Maybe it some DNS lookup failure causing temporary glitches?

No speed problems here.  This really does look like some kind of problem on different routes, not anything to do with Wowhead at all.

might be worth checking out yslow (firefox plugin)

will give you a much better indicator to what's actualy taking ages to load.

I used to be badly affected by this but I have had no recent issues. I've changed nothing my end so, as TL suggests, perhaps it is a routing issue.
Title: Page Load Delays
Post by: Gandalf on June 01, 2009, 08:24:40 AM
I have made brightstar aware of this and c4l is the most likely culprit. Unfortunately they have the best interconnects to multiple places!

It will be a big help if you can post traces in so we can see what your route to the server is to help narrow down the issue.

I'll also monitor the server, as it may be a CPU thing. (This web server is getting a lot more traffic than it used to)

Title: Page Load Delays
Post by: TeaLeaf on June 01, 2009, 10:48:26 AM
I have no page performance problems, but throughout this post I am waiting for "transferring date from Google-analytics", so I tend to think it is route specific to people from time to time.  Not sure what else to say until someone with the problem can post some pingplotter logs maybe or some travert showing the problem.

Just had a look at the source and noticed the link to the wowhead power.js file is in the html head section. It might help to move it to the bottom of the page. This way any slow downs with wowhead are less likely to effect non wow users.

QuoteThe problem caused by scripts is that they block parallel downloads. The HTTP/1.1 specification (http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.1.4) suggests that browsers download no more than two components in parallel per hostname. If you serve your images from multiple hostnames, you can get more than two downloads to occur in parallel. While a script is downloading, however, the browser won't start any other downloads, even on different hostnames.
http://developer.yahoo.com/performance/rules.html#js_bottom



Might be worth a try??

Post by: Gandalf on June 01, 2009, 12:57:43 PM
Ok, just checked the site and there is an updated vesion of the plugin with a local copy of the power.js

This is now installed on the server so it should improve load times. Please do let me know if this has solved the occasional slowdowns.

Also noticed the defer attribute, will be interesting to see if that helps. Not sure if it will with firefox as I believe there was a bug, might be fixed by now though.

Well I could enable HTTP compression, BUT with the advent of broadband this will actually slow the website down as the server has to compress the page, send it to your client which will then have to decompress the page to display it.

ahh k, as i said i dont really have much knowledge about this type of stuff, but the site gives me the impression we actually got a bit of delay on our site.. the yellow colors on the left is afaik the delay before the first bit of the files are received..

Title: Page Load Delays
Post by: Jamoe on June 02, 2009, 12:21:35 PM
yea that seems to have worked.

While I was checking out the power.js I noticed it pulls in css files from the wowhead server. Even after this update it still does this, seems bizzarre to me to have a copy on our server that still fetches css from wowhead. It might be dynamic though (not sure why the url starts with static).

i.e.

http://static.wowhead.com/widgets/power/power.css?3


Also noticed this in yslow (on this thread)

QuoteThe components are split over more than 4 domains


  • //www.deadmen.co.uk
  • static.wowhead.com
  • //www.google-analytics.com
  • images.wikia.com
  • rcm-uk.amazon.co.uk
  • rcm-images.amazon.com
The Domain Name System (DNS) maps hostnames to IP addresses, just like phonebooks map people's names to their phone numbers. When you type URL //www.yahoo.com into the browser, the browser contacts a DNS resolver that returns the server's IP address. DNS has a cost; typically it takes 20 to 120 milliseconds for it to look up the IP address for a hostname. The browser cannot download anything from the host until the lookup completes.


We seem to have a few bottle necks all over the place.
