Hi all, We've got a single xrootd server serving out BaBar root files over the WAN. We notice that there is a lot of inbound traffic, even though our files are exported read-only. Attached is a network plot showing the traffic on the xrootd interface for four simultaneous user analysis jobs. (In case you can't see the attachment, the inboud traffic tends to be about 75% of the outbound traffic.) Is this expected behaviour? Thanks, Kyle
