I just told the D-Cache team, and they where delighted that things have not yet broken for you, thier instant answer was can we have performance numbers
So please when you have got more results tell us all and I will pass on your good new to D-Cache.
Patrick also asked if he could quote you as having installed xrootd for D-Cache.
I guess that will have to wait a little, until all the tests are run

Owen

Hi,
Having just fixed my other problems on my dCache system I thought I'd
create some more for myself.
But disappointingly this just seems to work. Installation was as per
this instructions and straight away I was able to run some of the BaBar
tools against it.
I'll run a few more tests against it but so far it looks good.
Chris.
One more step in BaBar's plan for world domination done. Mwahahahah!
