Hello,

We're using nginx-1.2.8 to stream large files size 1G but found the
slow stream with high utilization of harddrive using command "iostat -x -d
3"

Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s
avgrq-sz avgqu-sz await svctm %util
sdc 0.00 444.00 78.67 7.00 18336.00 3608.00

16G Ram
8X CPU E31240
HDD SATA

Following are the main nginx configuration :-

http {
include mime.types;
default_type application/octet-stream;
#tcp_nopush on;
client_body_buffer_size 128k;
client_header_buffer_size 128k;
client_max_body_size 1200M;
keepalive_timeout 10;
ignore_invalid_headers on;
client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;
reset_timedout_connection on;
#gzip on;
access_log off;
include /usr/local/nginx/conf/vhosts/*;

}


Would be very thankful If someone could help me with better configuration
of nginx to reduce HDD-utilization.

Best Regards..
