Just take any big file that has more than 1000 bytes (for 1000 files with content). There are lots of them on your computer. Then do (for example):

This is instantly fast.

Or a bigger file:

This took only 0.253 seconds for creating 10000 files.

For 100k files:

Only 1.974 seconds for 100k files with about 5 bytes each.

Random Text File Generator

If you only want files with text, look at your /etc directory. Create one million text files with almost random text:

20.203 seconds for 1M files with about 2 bytes each. If you divide this big file in only 10k parts it only takes 0.220 seconds and each file has 256 bytes of text.
