I can create 400+ file system for each users,
but will this affect my system performance during the system boot up?
Is this recommanded or any alternate is available for this issue.

Pretty sure this is covered in the manpages for zfs(1m) and
zpool(1m).

When I reboot the gate machine, which has around 2000 datasets
attached, the zfs import step takes about 2 minutes.

I'd use something like this:

for user in $LISTOFUSERS; do
        zfs create -o quota=500Mb -o mountpoint=/export/home/$user \
                poolname/$user
done



blinder:hook $ pfexec zfs create -o quota=500Mb -o mountpoint=/scratch/pkg/test1 sink/test1
blinder:hook $ zfs list sink/test1
NAME         USED  AVAIL  REFER  MOUNTPOINT
sink/test1    31K   500M    31K  /scratch/pkg/test1
