After you finish with this, I suggest you complete the steps in this article if you're looking to max out the speed of your vbulletin.

List of Paid CDN's:

Amazon CloudFront $0.150 per GB. A decent offering from Amazon. But supports origin pull ONLY from Amazon S3 which you have to pay extra.

High Winds CDN $0.075 per GB. One of the cheapest you can get. No POP (point of presence) in Asia Pacific, yet. VPS.NET is reselling this. Original price is $0.50

Cachefly $0.39 per GB ($99 plan prorated). Expensive because it is a monthly plan. Said to be of high performance. Decent POP list. 30day trial available. There is a high volume plan and price can go as low as $0.03.

Limelight Networks $0.22 per GB (PAYG). Similar to CloudFront. You need to keep the files with them. They have $0.01 for each request if your file sizes are smaller than 250kb! Rackspace is a reseller.

Internap $0.18 per GB (250GB plan). They have good coverage around the world. SoftLayer is reselling Internap accounts.

Voxel $0.20 per GB. They have good coverage around the world. Also offers pro-apache support through their extension.

MediaTemple This service is $20/Month. This includes 200GB bandwith/month. If you go over that limit, here is the pricing for that [$.15/GB up to 10TB] [$.10/GB over 10TB]. They claim to be "25% faster in delivering content when benchmarked against competitive CDNs".

Is there a way to have all attachments stored at a cdn?

[final kaoss]

I'll have to look that up & post back.

Have you tried this yourself? The instructions are meant to work for their pull zones.

AFAIK this does not work for css files, avatars, attachments, custom profile pics, signaturepics nor any other user generated files. The issue is that vbulletin has only one location for files and cannot set a different location for writing the files to (your server) and reading the files from (the CDN).

[OldSchoolDSL]

I'll be the noob and ask....

cdn ?

i made a thread to do something like this, but i use a plugin to rewrite the URLs on the templates
maybe that can be usefull here too

[final kaoss]

A plugin for this would be helpful for alot of people, is it your own? If not, can you give us a link to it?

hi, near middle of the article under "plugin" http://www.vbulletin.org/forum/showthread.php?t=246277

I wonder how a CDN based on geoip will do.
for example, using examplex.com for country x and exampley.com for country y.
ofc examplex and exampley are two different servers hosted on two different countries.
the main problem seems to be the synchronization between files/writing files.

* Click on [Add New Replacement Variable] link and set it as follows:
o Set Search for Text to href="clientscript
o Set Replace with Text to href="http://cdn.mywebsite.com/clientscript

Block Disabled:      (Update License Status)

Avatars & Pictures - Storage Type

* Visit Avatars > Storage Type and set them as follows to match your above CDN rules by moving all of them to file systems:
o Avatars are currently being served from the filesystem at ./customavatars
o Profile pictures are currently being served from the filesystem at ./customprofilepics
o Signature pictures are currently being served from the filesystem at ./signaturepics

How Do I Test Images And Other Media Files Are Cached Or Not By CDN? Use curl to test HTTP headers (look for Etags, max-age and Expires headers):

Today I started using Cloudflare which comes with URLJET. Not sure if it's working yet.

[final kaoss]

Yes as long as you setup cloudflare properly it does fine.

16,066 requests saved by CloudFlare
32,112 total requests

But be aware that it is not a recognized CDN according to pagespeed, yslow & gtmetrix.
