Subject Dn/Rdn/Ava refactoring : results
Date Mon, 09 May 2016 10:38:00 GMT
Hi !

that's it, I'm done with the refactoring. All tests are now passing
green, even some that were ignored in trunk (typically things like DN
with multiple Avas).

I have ran a small test, parsing various DN with 1 to 4 RDNs on trunks
and on my branch, here are the results on 10 000 000 iterations each time :

             trunk             branch
         Nb secs   DN/s    Nb secs   DN/s     Ratio
1 RDN  : 25.787  387,792    8.852  1,129,688  x2.91
2 RDNs : 42.046  237,835   13.686    730,674  x3.07
3 RDNs : 54.950  181,984   18.376    544,188  x2.99
4 RDNs : 71.361  140,133   24.289    411,709  x2.94


Those benchmarks were conducted with a SchemaManager.

Bottom line, this is a x3 speed up ! I never expected that... OTIH, that
means what we were doing was frankly bad :/

I'll commit the branch, and then work on ApacheDS and Studio to have
them working well with the branch (all of that will be done in branches
too).

I'll come with a list of changes I have done in the APi for you guys to
review them and provide some feedback.
