Incredibly Slow Download Speeds Persist

[David Webster]

All,

I am still seeing Fiji to SoCal download speeds ~12 Kb/sec. I did a
quick survey and found that others in the USA, with different ISPs
(e.g. Wayne Rasband), saw similar rates. Apparently this doesn't occur
within in Europe. Also downloads from other European sites are OK.
This problem needs to be solved as 1.5 hour download times are
impractical. Since many users are see'ing the problem, I think that
someone responsible for Fiji needs to check with their ISP to see if
something can be done.

Testing... testing...  I currently get 700k/sec to San Diego, SoCal.

First of all, we're not on an ISP, but (as you can check easily for
yourself) on the DFN, the German academic network, which is supposed to be
pretty fast.

Second, I do not have problems fetching Fiji from a machine in Scotland I
have access to, with +1MB/sec rates.  So I doubt there is _anything_ I can
do; Scotland is well outside of the realm of any company I could make
responsible for slow connections.

Third, a quick traceroute to the IP I guessed from the web logs to
be yours reveals that the slow-down is in the telia.net and rr.com range:

As you can see, the dramatic lags happen to occur well outside of DFN.

Of course, you could provide some suggestions as to how we could overcome
the problem.  But these suggestions should be something I can do, me being
short of a magic wand and the surname "Potter".

You might be delighted to learn that Nico Stuurman (of MicroManager fame)
offered some webspace for a Fiji mirror:

        http://valelab.ucsf.edu/~schindelin/

This is also linkt from Fiji's main and download pages.

Thanks to Nico, this link ran at about 1 MB/sec or 50 times fast than direct
link to pacific.mpi.
