Forum:Random site slowness

At least at WikiDex we're experiencing site slowness since the last two days. Some pages are loading normally, but others took several minutes to load. And it seems completely random. Sometimes is recentchanges, sometimes a category page, sometimes previewing the edit changes, sometimes on save. It's not my internet connection, because viewing the site from work has also random slowness.

The browser says "Loading..." but no content is displayed. It could take several minutes to load, specially large pages (you could try one from c:es.pokemon:Categoría:Lista de Pokémon). It seems like the aticles with more internal links needs more time to load. For example, c:es.pokemon:Eevee tooks more time to load than c:es.pokemon:Ditto, because the first one has more internal links, but both takes extremely more time to load than c:es.pokemon:Cómo entrenar bien a tus Pokémon that has no links but has more content. It happens while logged in and logged out, with IE and Firefox.

Is it happening in other wikis? Please help! --Ciencia Al Poder (talk) -WikiDex 17:27, 21 December 2007 (UTC)


 * Oh, wait. The problems are not the internal links. The problems are the images. We use images as a representation of the type of each attack. The same page without those images is more fast to load (but still takes more to load than normally) --Ciencia Al Poder (talk) -WikiDex 18:03, 21 December 2007 (UTC)


 * Hmm, c:perfectworld:Monster_List has the same problem. It tooks several minutes to load because it has images for elements. Other pages without images are fast to load. It's a huge problem on our wiki because there are many articles with that system of images. I don't know if it's related to the upgrade, but if it's possible to get back the previous MediaWiki version in this wiki it would be great, because we couldn't edit until it gets fixed! --Ciencia Al Poder (talk) -WikiDex 18:13, 21 December 2007 (UTC)

Same with Zelda Wiki; it was really slow the past two days. I think it's due to the MW1.12 upgrade.--Richard 18:24, 21 December 2007 (UTC)


 * I'd done a temporary solution: I'd deleted all the type images and the load of the page is now normal, but articles looks crappy with all those red links. I reuploaded all the images with a different name and made a script that replaces the links to upload the images with the reuploaded images. This makes a client-side load, but I guess that technical team is on holidays and I have no chance. --Ciencia Al Poder (talk) -WikiDex 15:13, 22 December 2007 (UTC)


 * The same thing's happening over at the Nintendo Wiki. The Super Smash Bros. Brawl page can take forever to load, though it's probably because of the size (it was originally over 80 kb, though I've reduced it to 66).


 * The problem is not the length of the page. The problem is the number of images it contains, even if is the same image several times. --Ciencia Al Poder (talk) -WikiDex 17:23, 22 December 2007 (UTC)

At the StarCraft wiki I've been getting something similar over the past two days, but it affects the whole site, not just pages with images. For instance, I got an error message here: http://starcraft.wikia.com/index.php?title=Into_the_Darkness&redirect=no

This request could not be forwarded to the origin server or to any parent caches. The most likely cause for this error is that:


 * The cache administrator does not allow this cache to make direct connections to origin servers, and
 * All configured parent caches are currently unreachable.

Yesterday the pages took a really long time to load but actually did, and there were no error messages. This might be a different problem though. PsiSeveredHead 01:41, 23 December 2007 (UTC)

We're definitely working on this. Johnq (talk) 01:55, 24 December 2007 (UTC)

Not so random (related?)
The page c:fr.guildwars:Utilisateur:Jaxom/Uriel Altair is loading very slowly in Internet Eplorer 7 (maybe other version too) and Firefox (if it ever load). It's a user page so it's not so important but if it's slow on my 7.1Mbps câble connection... That user live in New-Caledonia and internet there is already slow enough.

So, is it related ? I saw a weird message in the line at bottom of IE windows saying in french "Url nuisible" followed by an url to a publicity (not sure if it was of Google). Not sure about the meaning. If i try to translate in english; it say something like "bad URL" or "damaging URL".

Thanks for advice. Note that i've already tried to purge it and nothing changed. — TulipVorlax 10:28, 24 December 2007 (UTC)


 * Confirmed: The problem are the images: It has several images. You always could do a test: A page with lots of images and the same page without images. The result is that the page with images needs more time to load, higher when more images it has --Ciencia Al Poder (talk) -WikiDex 10:39, 24 December 2007 (UTC)
