[Genome] Performance of genomebrowser or network ?

[Hiram Clawson]

Good Morning Kees-Jan:

You can test your connection speed between the locations that appear
to run slow and the locations that appear to run faster with a download
of a test file to get a measurement of transfer speed.  Try this rsync
command in the two locations:

rsync -a --progress rsync://hgdownload.cse.ucsc.edu/gbdb/ce4/ce4.2bit .

That is a simple 25 Mb file.  I note transfer times from different
test sites that I have access to range from 2 seconds to over 10 minutes.

You should be able to note a difference in the two locations you
test from.
