#!/bin/sh
zfs destroy -R castiana/testzfs
rm -Rf /tmp/testzfs
zfs create castiana/testzfs -o mountpoint=none
zfs snapshot castiana/testzfs@base
mkdir /tmp/testzfs
clone() {
echo "Creating ${1} clones"
BASE=$(date +%s)
for i in $(seq ${1}); do
UUID=$(uuidgen)
zfs clone castiana/testzfs@base castiana/testzfs-$UUID -o
mountpoint=/tmp/testzfs/${UUID}
done
END=$(date +%s)
TOTAL=$((END-BASE))
PER=$((${1}/${TOTAL}))
echo "Took: $TOTAL seconds ($PER/s)"
}
clone 100
clone 200
clone 400
clone 600
```
That's on an up to date artful system. I'll do a similar test on an up
to date xenial system.
