FTR, here are the results for DN parsing when we don't have a
SchemaManager :
trunk branch
Nb secs DN/s Nb secs DN/s Ratio
1 RDN : 5.959 1,678,134 5.198 1,923,817 x1.15
2 RDNs : 10.015 998,502 8.197 1,219,959 x1.22
3 RDNs : 12.458 802,697 9.820 1,018,330 x1.27
4 RDNs : 16.382 610,426 13.029 767,519 x1.26
As you can see, the gain is only around 25%. Also, comparing those
results with a SchemaAware DN parsing shows that it costs 80% more when
we have a SchemaManager involved (in the branch), and up to 4.30 times
more in trunk...
That means the server will certainly benefit a LOT from these
improvements, which will not be necessarily visible for the clients.
