| > I'm assuming whatever file system is on the disks... Netflix uses UFS+J on FreeBSD 10. Here are some notes from their talk at NYCBSDCon 2014: - 400,000 stream files per appliance. - 5,000 - 25,000 client streams per appliance. - 300 - 500 streams coming off each disk all the time. - Attempt to buffer 1MB ahead, but caching is futile. - Result is completely random disk workload. - System becomes limited by disk latency and CPU load.
