Hi Steve,
Here's some rate data using lcg-cp, may help spot some trends if you
care to do a bit of mining. Rate in kB/s (reported by lcg-cp using a
1GB file)
[plove@fal-pygrid-32 plove]$ rgma -c "select MeasurementDate,Rate from
TransferRates_v04 where CEName='fal-pygrid-18.lancs.ac.uk' and
SEName='dcache.gridpp.rl.ac.uk' and MeasurementDate>'2006-07-01' and
Message='OK' order by MeasurementDate DESC, MeasurementTime DESC"
