with "ls -f" on 1.9M files its 45 seconds, much better than regular ls (and system load of 94)

2.25M and its 60 seconds

I'm also spamming about 16-18 thousand new files per second to disk using a very inefficient set of csh scripts...

A more efficient one-liner:

    seq 1 8000000 | xargs touch

Interestingly, that didn't work.

Strangely "jot -w file 8000000 1 | xargs touch" worked.

I'm going to try to replicate this because I sense some kind of tomfoolery.

The command I quoted works verbatim on one of my Ubuntu systems. It's ~60X faster than eg "for i in $(seq 1 8000000); do touch $i; done" because it creates many files per fork+exec, and fork+exec is a much heavier operation than creating an empty file.

Seq isn’t installed by default in FreeBSD, while jot is. That’s all. I think seq may be part of coreutils and installed as ‘gseq’? Not entirely sure.

seq is in /usr/bin, its default in FreeBSD as on FreeBSD 9.

I'm actually not sure why it failed after generating 1.3M files, no error messages or anything, it was weird. Initially I thought maybe it was like an inode/fd issue or something but no.
