Serving audio files exemplifies the use of AIO. The MP3 location is as follows:

# MP3 files are served using AIO where supported by the OS.

location ^~ /sites/default/files/audio/mp3 {

location ~* ^/sites/default/files/audio/mp3/.*\.mp3$ {

And Ogg/Vorbis location is as follows:

# Ogg/Vorbis files are served using AIO where supported by the

OS.

location ^~ /sites/default/files/audio/ogg {

location ~* ^/sites/default/files/audio/ogg/.*\.ogg$ {

These have the following lines in common:

directio 4k; # for XFS

tcp_nopush off;

aio on;

output_buffers 1 2M;

}
