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.

MmS1,

Do you use nginx webserver? I have no problems with full attachments (not thumbs), but this option work ONLY with nginx. With other webserver "nginx acceleration" must be disabled, see FAQ. Don't enable all mod options "just for fun", if you don't have nginx webserver.

If you use nginx, but full attaches can't be downloaded, check twice absolute path to directory (see config samples in FAQ)

Try to re-read FAQ and my explanations on previous page.

This is the config I used when I had your mod working AND vBSEO attachment rewrites going. Now from the site, everything worked. In fact, load even when down. Yet I'm not sure if it's correctly working or not.

Notice I did not add your config options as this seemed to work.

server {
listen   80 default;
server_name www.xxxx.com xxxx.com;
server_name_in_redirect on;


location / {
root   /www/vhosts/xxxx.com/htdocs;
index index.php;
autoindex on;
access_log off;

}

location ~ \.php$ {
root           /www/vhosts/xxxx.com/htdocs;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
include   fastcgi_params;
fastcgi_intercept_errors	on;
}


location /forum/ {

if (!-e $request_filename) {
rewrite ^/forum/(.*)$ /forum/vbseo.php last;
}

}
if ($request_filename ~ "\.php$" ) {
rewrite ^(.*)$ /forum/vbseo.php last;
}



location ~* \.(swf|pdf|ico|css|js|gif|jp?g|attach|thumb|png)(\?[0-9]+)?$ {
expires max;
root 	/www/vhosts/xxx.com/htdocs;
}



location /status {
    stub_status on;
    access_log   off;
}

 }

[Vitaly]

At first glance, that can work

IMHO, there are no reasons to add "expires max". Very cheap economy, but potential problems with browser cache, if you upload new CSS for some mod and so on.

[mindhunter77]

ok, set at 30d; ??

[Vitaly]

No. Remove it at all.

[mindhunter77]

ok,

For those who want to test this mod with vBSEO still handling your attachments this is my working conf file nginx. This one is updated from the last one I posted and has some fixes. Keep in mind a few things.

1) In my conf where it says /thumbnails is not attachment thumbnails, I embed flv video on my site and this is where the flv thumbs go. You will not need this.

2) I placed this in the mod config area, and have both options set to YES.

/forum/uploadedimages

3) My server was running between 2.00 and 3.00 at all times before this mod, it now runs at 1.0 or less. I could probably get it even lower then that if I disabled the handling of attachments through vBSEO all together, but I get a lot of google image traffic and don't want to risk loss of ranks.

4) My forum gets about 50,000 unique per day, 90% of all threads contain pictures and video with picture thumbnails at 400px.

server {
listen   80 default;
server_name www.xxxx.com xxxx.com;
server_name_in_redirect on;



location / {
root   /www/vhosts/xxxx.com/htdocs;
index index.php;
autoindex on;
access_log off;

}

location ~ \.php$ {
root           /www/vhosts/xxxx.com/htdocs;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
include   fastcgi_params;
fastcgi_intercept_errors	on;
}



location /forum/ {

if (!-e $request_filename) {
rewrite ^/forum/(.*)$ /forum/vbseo.php last;
}

}
if ($request_filename ~ "\.php$" ) {
rewrite ^(.*)$ /forum/vbseo.php last;
}


location /forum/uploadedimages {
root    /www/vhosts/xxxx.com/htdocs;
expires 24h;
}



location /forum/thumbnails {
root    /www/vhosts/xxxx.com/htdocs;
expires 24h;
}


location ~* ^.+\.(gif|png|ico|css|zip|tgz|gz|rar|pdf|bmp|js|swf) {
access_log   off; 
expires 24h; 
root 	/www/vhosts/xxxx.com/htdocs;

	}


location /status {
    stub_status on;
    access_log   off;
}

 }

[mindhunter77]

nginx is a webserver, for this to work 100% you need to be using nginx as your webserver, your host may not just switch that for you, you will have to ask them

[MmS1]
