Dave,
If Ben's measurements are in KBytes not Kbits, then they would agree with
your comments:
HTTP
====
chiefwigham - 275 kB/s = 2.2Mb/s
brendan - 301 kB/s = 2.4Mb/s
FTP (downloading)
===
chiefwigham - 283 kB/s = 2.3Mb/s
brendan - 347 kB/s = 2.8Mb/s
FTP (uploads)

chiefwigham - 192 kB/s = 1.5Mb/s
brendan - 180 kB/s = 1.4Mb/s
Ben - can you clarify?
Has anyone else done any benchmarking on production machines?
Thanks,
Mark.
