vB Accelerator
Mod Version: 0.4, by Vitaly

This mod is suited for medium and big boards. It reduces server load, caused by thumnails and big attachments.

what's the problem with?

1. In original vB all thumbnails a downloaded via php. So, if you page contains 10-20 attached images, then each page php request will be followed by 10-20 thumbnails php requests. That's very bad.
2. When attachments body transfered via php, that's much more waisteful, than direct transfer of static file. Especially for big files.

what this mod does:

1. All thumbnails will have DIRECT links (served as static files). Much lower reply latency and server load.
2. If you have http://nginx.net/ webserver, you php-fcgi will not participate in file transfer any more. It will reply with X-Accel-Redirect header. Then nginx will proceed attachment as static file.
   • No more problems with multiple downloads of 10-mb files.
   • No needs to restrict attachments and full-size images for guests and search bots.
3. That works for forum posts, blogs, albums. Everywhere!

how to install:

1. Make sure, this files are stored on disk, NOT in database:
   • post attachments & thumbnails
   • blog attachments & thumbnails
   • album images & thumbnails
2. Make sure, that thumbnails are in web-accessible area. If not - reconfigure your web-server first. If you own big board - then you know how to do that .
3. Check manually, that you can download any .thumb file via browser.
4. Import this product, and set options for you configuration.
5. Be happy to reduce server count in your cluster

PS. It's tested and works fine at my production site for 1 week. But I'll be happy to know server load statistics from big boards owners.
