Nofri, Apa kabar? Did you check for enqueue contention on the VTOC? Your Delete/Define was probably stuck behind that. Check the RMF Enqueue report.
It's unlikely that DEFRAG by itself will generate enough IO to degrade a single volume's performance unless the volume is already very busy before the defrag starts.
