High-performance statistics

A system for allocating memory to a thread of a multi-threaded program, the system comprising:

• a programmable processor;
• and
• a machine-readable medium storing instructions that, when executed by the processor, cause the at least one programmable processor to perform operations comprising:
• prefix, to each statistics object of the one or more statistics objects, an object header having an owner identifier to identify an owner of the corresponding statistics object and a version counter with an initial version count of zero to indicate a new statistical object, wherein an even version count indicates an invalid statistical object and an odd version count indicates a valid statistical object;
• associate each statistics object with a statistics class instance, each statistics class instance being associated with an associative registry that is configured to allocate smallest possible objects of a size equal to or greater than to that of the one or more statistics objects, the associative registry segmenting the statistics objects according to a size class;
• construct each allocated statistics object in the object frame after the object header;
• and
• initialize the object header of each allocated statistics object by executing a store/store memory barrier and incrementing the version counter by a count of one to mark the associated allocated statistics object as valid.
