Hi everybody,

I'm relieved to be able to report (a) that I've been able to replicate
Jeremy's observations of weirdly low upload speeds in the Flash client
by running tests against the server that he set up, and (b) that the
performance disparities exhibited by that server do not appear to show
up in the M-Lab test environment.  So I *think* whatever problem he
encountered is likely the result of some misconfiguration on the
server itself, rather than any specific problem with RC3.
