Abstract: For mainstream multi-core processors,the VTD-XML’s node query execution performance was optimized,based on preload method,and from the concurrent execution of multiple threads and thread memory access perfor-mance.The experimental results show that the multihreaded XML document parsing framework proposed in this paper can take full advantage of the computing resources of multi-core processors,and effectively improve thread memory access performance,greatly improve the performance of XML node query.

Key words: VTD-XML,Chip multiprocessor,XML node query execution optimization,Multithread
