Transfer Channels

Back to 'proper' work, and I realised that the transfer-channel sizes are still very conservative (with the exception of Imperial). Rather than just increasing to a high value, I thought I'd plot some timings to show the difference of a 0.5TB FTS session.

The 4 steps on the image show: seeding to ral-T2 with lcg-cr from local workstation, then 3 sets of transfers up to uki-scotgrid-glasgow with the files setting on the transfer channel to 5,10 and 15 respectively.

My script *should* have continued with larger steps, but some of us forgot to renew the voms-proxy...
