SummaryIf you want to have good performance for your singleton implementation and you need to provide a constructor, you should go for the static data member implementation. In case you can default the default constructor, the two implementation strategies are equivalent performancewise. I would suggest using the block local approach as it saves having to define and initialize the singleton object in an implementation file.
