How fast is the SRB?
For transferring large files, SRB will normally be significantly faster than FTP, SCP, or NFS and the like, because of the SRB’s parallel I/O capabilities (multiple threads each sending a data stream on the network). Sreplicate and Scp use parallel I/O for large-file data transfers by default, and you can use the -m option on Sput and Sget to select parallel I/O. For small files, transfers can be a little slower due to the additional interaction with the MCAT (especially to a remote MCAT), but you can use Containers and/or Sbload (Bulk load) and Sbunload (Bulk unload) to greatly speed these. For more information see, the man pages and Containers questions in this FAQ. We are working toward enhancing Sget and Sput to do bulk operations to non-container files to speed them up too.
