Yes, `dirEntries` isn't as fast as it could be.
Here is a directory iterator which tries to strictly not do more

When I examine the process with strace it appears that the ftw

Great. I did not use -O with my test. It may have to do something with

However, ftw performs about twice as fast as dirEntries (despite some
