Make slapadd faster?

I know you can disable some checks to make slapadd faster. But I think 
in my test vm with limited disk iops, it looks like this disk io is the 
problem.
I am not sure how slapadd adds entries, I guess one at a time? You could 
get a significant improvement by reading more entries and writing more 
entries at once? And if such a batch transaction fails you can always go 
back to submitting the transactions of the batch one by one, to identify 
which one is failing.
