Forum slow with skin with adv

[hollyboy]

Hi,

my forum is slow when users use the default skin:
http://www.interfans.org/forum/?langid=1&styleid=35


With the Vbulletin skin (less adv banners) runes faster:
http://www.interfans.org/forum/forum.php?styleid=28

In particular browser Firefox and Ie are extremely slow. Chrome works better.

What is the issue that slows down my site?
My adv or other scripts?

Your site is attempting to load various ad scripts and what not that can't be reached, causing a strain on the server:

Yes there are adv banners on my site.
What should I do about them?

[Gio~Logist]

Switch your ads to ones that actually load and are optimized. The ones you have dont even seem t be loading.

Mmm actually the banners all show so I am confused

No forum optimization needed?

[Gio~Logist]

Oh, hah! So sorry, forgot I had ad blocker enabled.

Yea, some optimization is definitely in order. You're making various calls to 3rd party scripts, fonts and css files that are all loaded from other servers. This means before your site finished loading, it needs to request all of these resources from other websites.

Attached is a screenshot with some of the resources and the timeline.

I would try and consolidate as much as you can into single js and css files and look into hosting them locally and compressing them or use a cdn.

Also of course make sure you're not calling resources you don't even need (ie: old mods, old code, etc)

Here's why your forum is slow....

And as for redirects...
You have alot of work to do... click on Minimize Redirects on that report to see the very long list.

Also, holy crap dude... 1.2MiB of JavaScript is parsed during initial page load. My total page size is under 300KB.. just your JS outweighs my page by quite alot.

I know, in fact skin with no adv runs faster

Because default skin has more than 6 times less requests then other skin.

91 Requests : https://gtmetrix.com/reports/www.interfans.org/Rn64GE4Q
602 requests : https://gtmetrix.com/reports/www.interfans.org/sEACuXaL

The question is how can I fix this?
