Network Tests

I have introduced some network tests. Test jobs are sent to every UK site once an hour which attempt to copy a number of differently sized test files (1MB, 5MB, 10MB, 50MB and 100MB) from the Storage Element at each of the sites. The transfer times are then used to calculate the average throughput in MB/s. The results are averaged over the last 24 hours to produce a matrix of site to site transfer throughputs. There is an average over the whole matrix on the main UK Grid page. See http://pprc.qmul.ac.uk/~lloyd/gridpp/nettest.html.
