Best file system for serving 1GB files using nginx, under moderate write, read performance-wise?

Question

I\'m going to build large files server, and need stack-overflow community advice for file system choice (linux).

File server is going to serve 1-2GB sized static files

Answer 1

To provide best results with serve heavy content, there is something else to tune. Please take a look at Nginx core developer's comment below:

1. Switch off sendfile, it works bad on such workloads under linux due to no ability to control readahead (and hence blocks read from disk).

   sendfile off;

2. Use large output buffers

   output_buffers 1 512k

3. Try using aio to ensure better disk concurrency (and note under linux it needs directio as well), i.e. something like this

   aio on; directio 512;

Other recommendations:

1. Check the filesystem swap is not used

2. Filesystem - ext4, xfs. Good to enable data_writeback and noatime mount options
