Test thread (large image attachments)

Thanks, Matt!

 

I made a few changes (shown in orange) to /usr/local/nginx/conf/nginx.conf

Hard to tell on my speedy home internet connection, but I think they are helping. I disabled the CDN on my site, and there have been no complaints so far

Code:

events {
    worker_connections  8192;
    accept_mutex off;
    use epoll;
    multi_accept on;
}

http {
 aio threads;
 pagespeed ImageMaxRewritesAtOnce -1;
 map_hash_bucket_size 128;
 map_hash_max_size 4096;
 server_names_hash_bucket_size 128;
 server_names_hash_max_size 2048;

#limit_req_zone $binary_remote_addr zone=xwplogin:16m rate=40r/m;
#limit_conn_zone $binary_remote_addr zone=xwpconlimit:16m;

more_set_headers "Server: nginx centminmod";
more_set_headers "X-Powered-By: centminmod";

include /usr/local/nginx/conf/vts_http.conf;
include /usr/local/nginx/conf/geoip.conf;
include /usr/local/nginx/conf/maintenance.conf;

include /usr/local/nginx/conf/pagespeedadmin.conf;
include /usr/local/nginx/conf/fastcgi_param_https_map.conf;

log_format      main    '$remote_addr - $remote_user [$time_local] $request '
                '"$status" $body_bytes_sent "$http_referer" '
                '"$http_user_agent" "$http_x_forwarded_for" "$gzip_ratio"'
                ' "$connection" "$connection_requests" "$request_time"';

error_log   logs/error.log error;

    index  index.php index.html index.htm;
    include       mime.types;
    default_type  application/octet-stream;
    charset utf-8;

        access_log off;
        sendfile on;
        sendfile_max_chunk 512k;
        tcp_nopush  on;
        tcp_nodelay on;
        server_tokens off;
        server_name_in_redirect off;

        keepalive_timeout  60;
        keepalive_requests 1000;

Also, ngx_pagespeed seems to be nicely optimizing my image attachments (converting to webp, etc) even though they don't end in an image extension.

 

ngx_pagespeed makes a huge difference for the home page of my site: WebPagetest - Visual Comparison

 

Is there any chance that if I use that addon to move attachments to data folder that I would be unable to move them back if necessary at a later date?
