> The Modify operation is quite costly, as we do up to 10 lookup. Each lookup leads to
a ServerEntry clone, a costly operation. If we measure all the time consumed in such clone
operation, it goes up to 84% of all the CPU time.
> We can most certainly spare 8 or 9 lookups, speedup the operation by a factor 5 to 10.
