-x

Been debugging apparently slow transfers using FTS (now a 2.0 application....) and discovered a slight change in the UK setup.

Previously I just set the total no if files per channel, but I noticed that even with that set high, my dteam transfers were still only popping one file at a time off the list.

Turns out that the VO shares now have hard coded limits in which are only visible with the -x flag

ie:
glite-transfer-channel-list -x STAR-UKISCOTGRIDECDF
Channel: STAR-UKISCOTGRIDECDF
Between: * and UKI-SCOTGRID-ECDF
State: Active
Contact: lcg-support@gridpp.rl.ac.uk
Bandwidth: 0
Nominal throughput: 0
Number of files: 9, streams: 1
TCP buffer size: default
