You do not want to even consider small files ... this is not a good use case for a cluster file system in general. The only real way to deal with this is to put your backing file system on SSD or Flash, and have a very fast network. Even then performance is not going to be that good. -- Joseph Landman, Ph.D Founder and CEO Scalable Informatics, Inc. email: landman at scalableinformatics.com web : http://scalableinformatics.com http://scalableinformatics.com/sicluster phone: +1 734 786 8423 x121 fax : +1 866 888 3112 cell : +1 734 612 4615
