It hardly depends on the amount of objects you have.
In current LO implementation there is really huge drawback.
It creates 2 files for each LO. When you have > 10000 LOs you are
lost.

There was a patch made by me to provide LO support inside one table.

Without this patch I had approximatly 30 minutes to insert 10000 LOs.
With it it was only 5 min neccessary.

Also you should understand that all measures hardly depends on the
size of the LOs you will have. It would be easier for you just write
some small test cases on the random data and measure them.
