I tried the 64K release of xrootd. The obvious stuff all seems to work. (Took me a little while to spot that I needed a -t flag on the xrootd data servers, but once I woke up to that it ran fine.) The performance seems better than before, although my new hardware setup was likely to produce better performance. (We "optimized" the network between nodes to put them all on the same GB Ethernet switch card). I will acquaint myself with the code and see what I can find :-) -- Gregory J.
