Defrags Slow

Ive ran defraggler 3 times and each time its taken 7 hours. Ive run them a day apart its not like weeks where my drive would be fragmented badly.

I only have approx 931gb total and im only using 162gb. So Its not defragging a huge amount.

Is it operator error ? or is it normal for defraggler to take so long.

I also noticed like on other defrag software it doesnt have an optimize option.

Thanks for any help :)
