hi all,

```
        i am using upload module to post file to the server. how can

```

i improve scalability of the server to upload files . one server is  
running and receiving all uploded files . if i add three or four server  
on the backend .will it improve scalability?  
here is my configuration there is no need for backend server but if i  
add 3 or 4 backend server will it improve scalability?

i need good tuning to get more concurrency

worker\_processes 20;

error\_log logs/error.log notice;

working\_directory /usr/local/nginx;

events {  
worker\_connections 1024;  
}

http {  
include mime.types;  
default\_type application/octet-stream;

server {  
listen 80;  
client\_max\_body\_size 100m;

# Upload form should be submitted to this location

location /upload {

# Pass altered request body to this location

upload\_pass @test;

# Store files to this directory

# The directory is hashed, subdirectories 0 1 2 3 4 5 6 7 8 9 should

exist  
upload\_store /tmp 1;

# Allow uploaded files to be read only by user

upload\_store\_access user:r;

# Set specified fields in request body

upload\_set\_form\_field “${upload\_field\_name}\_name” $upload\_file\_name;  
upload\_set\_form\_field “${upload\_field\_name}\_content\_type”  
$upload\_content\_type;  
upload\_set\_form\_field “${upload\_field\_name}\_path” $upload\_tmp\_path;

# Inform backend about hash and size of a file

upload\_aggregate\_form\_field “${upload\_field\_name}\_md5”  
$upload\_file\_md5;  
upload\_aggregate\_form\_field “${upload\_field\_name}\_size”  
$upload\_file\_size;

upload\_pass\_form\_field “^submit$|^description$”;  
}

# Pass altered request body to a backend

location @test {  
proxy\_pass [http://localhost:8080](http://localhost:8080);  
}  
}  
server{  
listen 8080;  
}  
}
