I am running logstash with the following config

input {  
file{  
path =\> "D:/Log/_/MIP/_"  
start\_position =\> "beginning"

```
}

```

}

filter{  
mutate{  
gsub =\> ["path","D:/Log/", ""]   
}

}

output {  
stdout {  
codec =\> line {  
format =\> "%{path}"  
}  
}

```
            file{
		path => "Z:/Logs/%{host}/%{path}"
		message_format => "%{message}"
		flush_interval => 0

```

}

}

The input log file location is as follows  
D:\Log\3c238437-5e11-4c5c-bb16-c757794543b1\MIP\MipLogger.log

The file size is 84.7 MB

I am seeing its taking more than 30 minutes to get the output in the resultant shared location .Am I doing something wrong .If not what is the issue .

Below is my computer config

Windows 8  
Processor Intel(R) Core(TM) i7-4900MQ CPU  
RAM 16 GB

If you are looking for performance, you should probably not flush after every message, which is what setting the ['flush interval'](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-file.html#plugins-outputs-file-flush_interval) to 0 does. Stick with the default settings and comment out the stdout output and see what impact that has.
