Board Optimization - vB Accelerator

vb 4.0 version here

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 nginx 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.

This mod is developped here: http://github.com/rcdesign/vb-accelerator . Patches are welcome.

[mindhunter77]

how did you make the .thumb web accessible?

[mindhunter77]

is there a way to verify this is working, I think I finally got it all figured out but wanted to verify.

[mindhunter77]

Finally got this going I think, only one drawback from my site, it seems that this conflicts with this mod,

WATERMARK ATTACHMENTS
https://vborg.vbsupport.ru/showthread.php?t=201972

If I turn off Enable large downloads acceleration, the watermarking works again.

[mindhunter77]

Yea, mine look this

http://www.xxxxxxxxx.com/uploadedimages/1/20016.thumb?d=1222135419

So I guess it's not working

[MmS1]

It's oky working fine with me
But i can't download files pic's oky i can but files i can't

even the attachments convert them into direct link or just thumb only

[mindhunter77]

could someone who has this working post their nginx.conf so I can see what I'm doing wrong, this still isn't working.

For all, who think, that mod is not working:

1. Check that thumbnails are accessible via www (type URL to any thumbnail in browres path). Browser should offer to download file or to show thumbnail (if youcared about mime type)

2. Look into page source, and check "direct" path to any thumbnail. If pattern is different - fix appropriate mod settings.

3. Split your job in 2 parts:
- try to do direct thumbnails working first
- try to make work nginx accelerated download. DONT turn it ON with another web-server.

4. If you have VBSEO - don't enаble attachments rewrite.


Sorry, but can't consult everyone about each particular configuration . I hope, that general recommendations will help.
