Challenge: Disk bottlenecks

(cymbal ringing)…- [Instructor] Time for some challenges.…Let's just have you do little experiments comparing…the performance of file systems.…Try doing the create files for file systems types ext4,…btrfs, and xfs, creating 10K files of size one byte each.…See if there's a difference…between those three file system types.…Then try 1,000 files where each file is 10K bytes.…

Then, something a little bit different,…is there a difference in those file systems' time…when you create a directory path…that's 1,000 directories deep?…And after you create each directory,…do a sync and drop caches.…So you make a directory, sync, drop caches…and make a directory underneath that,…sync, drop caches, make a directory under that 1,000 deep.…Good luck!…
