Explore how to measure the performance of different filesystems doing different file and directory operations.
- [Instructor] Now let's talk about solutions…to the challenges.…So, we had an exercise disk that sh script 4…that did btrfs,…ext4,…and vfat…and the challenge we asked you to do ht4, btrfs, and xfs.…So, you just have to replace the vfat with xfs…and run the script a couple of times…with the file size and number of files.…Then, for the third challenge question,…creating a directory path that's a thousand directories deep…well, that's going to take a little bit of programming, so.…
Let's look at the results I got…and look at the code I wrote…to do the thousand deep directory.…I've got the result in a file.…I had done a type script command.…So, let's look at this.…So, I made directory temp foo…and that's where I'm going to have the script…create the directories and so forth.…So, the first time I ran it, file size one…and ten K files…and we see the results for creating the files…and for grepping the files…and I added to the script, the making the deep directory.…
Now, that's going to be redundant…because each time I run the script,…
