The issue you are facing:
I get long response times before a file starts downloading. The larger the file, the longer the response time. After the download starts, speeds are normal. I’m talking ~50s before download starts of a ~512Mb file.
Extra info: data folder is NFS share.
Sorry if this is an amateur question, but this is a home server and I am an amateur 
who’s not really familiar with coding (but eager to learn!)
