I in a very old machine simple to do the test, if open reserv mechanism, 
the ID generation speed can reach 50K/s. If turn off reserv mechanism, 
the performance will be dropped to 13K/s, performance degradation is 
very obvious, but off reserv will enable ID increase linearly with 
time, this aspect of the advantages and disadvantages can allow 
developers to choose their own.

In addition, the performance of IgniteAtomicSequence may related to the 
performance of cache nodes, therefore,AtomicConfiguration, whether it is 
necessary to add an attribute, similar nodeFilter such, let developers 
control a distributed datastructure cache deployed on the nodes with 
high performance.

The performance of AtomicSequence is very good as most of the operations
are local. The way it works is that it will reserve a range of numbers by
sending a request, but then will return all new IDs locally, until the
reserved range is exhausted.
