	The Metadata Performance Project is a joint project of the Lustre™ team, the ORNL LCE, and Cray initiated in early spring of 2009. Current areas of investigation include LNET, ''ptlrpc'', ''libcfs'', and the MDS server. The overall goal is to maximize single MDS performance through optimizations that utilize the multiple cores available in today's MDS machines.
