Wait, this is just nothing... I have played with the 
AttributesSerializer, and the gain is huge : more than 25% speedup 
against the server with Long. So it's around 30% faster than ADS 1.0 :)

The tests I have done this morning with YJP showed that readObject was 
responsible for 55% of all the time spent in the server. Improving the 
serialization of data will result in a massive gain (estimated to a 
speedup to 40%). As the best results we got last year with Ersin 4-cpu 
computer and JRockit JVM went up to 950 request/s, we can expect 
something like 1300 req/s. May be more :) And this will be 10% slower 
than FDS or 15% slower than OpenLdap for this kind of test ... (those 
numbers are *not* official !)
