ADS + Mavibot profiling results

Hi,

I ran some profiling on the AddPerfT with Mavibot, and found some
interesting results.

We spend 44% of processing time in index add() method, 33% in  the
updateRdnIdx() method, and 13% in the MasterTable.put() method.

While serializing the values, we create more than 1 million
ObjectOutputStream, which represents 18% of the spent time. This is
huge. I wonder if we can't use a better way to serialize elements, which
will result in way better performances.

More to come...

thanks for providing the profiling results
