Strange issue after nginx update

could you please help me solve this issue? I'm getting crazy! 

Before the nginx update my client worked perfectly: it posted files to my website without any delay. 

How, after nginx update (ubuntu 16.04 LTS) I've got this issue: 

- the client posts files successfully but the answer of the post is delayed. The more the file is bigger, the more the answer is delayed. 

I put a sniffer into the website' server and I noticed that the nginx receives the post but it waits to transfer the file to php-fpm process, so also the answer to the client is delayed 

The nginx server is: 

nginx/1.10.0 (Ubuntu) and its conf is: 

user www-data; 
worker_processes auto; 
pid /run/; 

events { 
worker_connections 768; 
# multi_accept on; 

http { 
sendfile on; 
tcp_nodelay on; 
keepalive_timeout 65; 
types_hash_max_size 2048; 
client_max_body_size 0; 
log_not_found off; 
server_name_in_redirect off; 
client_body_timeout 120s; 
autoindex off; 
include /etc/nginx/mime.types; 
default_type application/octet-stream; 
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE 
ssl_prefer_server_ciphers on; 
access_log /var/log/nginx/access.log; 
error_log /var/log/nginx/error.log info; 
gzip on; 
gzip_disable "msie6"; 
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript; 
include /etc/nginx/conf.d/*.conf; 
include /etc/nginx/sites-enabled/*; 

and website's php-fpm conf is: 

server { 
listen 80; 
server_name_in_redirect off; 
autoindex off; 
client_max_body_size 500m; 
index index.html; 
root /home/test/test; 
location ~ \.(php|html|htm|php3)$ { 
try_files $uri 404; 
fastcgi_pass unix:/run/php/mdtest-fpm.sock; 
include fastcgi_params; 

fastcgi_params config: 

fastcgi_param QUERY_STRING $query_string; 
fastcgi_param REQUEST_METHOD $request_method; 
fastcgi_param CONTENT_TYPE $content_type; 
fastcgi_param CONTENT_LENGTH $content_length; 

fastcgi_param SCRIPT_NAME $fastcgi_script_name; 
fastcgi_param REQUEST_URI $request_uri; 
fastcgi_param DOCUMENT_URI $document_uri; 
fastcgi_param DOCUMENT_ROOT $document_root; 
fastcgi_param SERVER_PROTOCOL $server_protocol; 
fastcgi_param REQUEST_SCHEME $scheme; 
fastcgi_param HTTPS $https if_not_empty; 

fastcgi_param GATEWAY_INTERFACE CGI/1.1; 
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; 

fastcgi_param REMOTE_ADDR $remote_addr; 
fastcgi_param REMOTE_PORT $remote_port; 
fastcgi_param SERVER_ADDR $server_addr; 
fastcgi_param SERVER_PORT $server_port; 
#fastcgi_param SERVER_NAME $server_name; 
fastcgi_param SERVER_NAME $http_host; 

# PHP only, required if PHP was built with --enable-force-cgi-redirect 
fastcgi_param REDIRECT_STATUS 200; 

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 

Thanks a lot,
