[TIGGE #BGR-338705]: A problem when perform LDM tests

Hi YangXin,

re: Do you mean kilobytes per second or kilobits per second?

> I mean kilobytes per second and megabytes per second.

Very good.  Your 700-800 KB/s and 1.0-1.3 KB/s numbers are what we would expect
for the CONDUIT feed.

re: please report statistics

I am still not seeing statistics from your machine.

I think that this _might_ be a good idea since it would identify packet shaping
for outbound connections if there is any.  I will leave this decision to your.
If you want to proceed, I will turn off the ingest of CONDUIT on 
yakov.unidata.ucar.edu
and start ingesting your data.

I agree: the transfer tests from yakov to your machine seem to indicate that 
there is
no packet shaping.  I want to wait on a final determination until I can see the 
real
time statistics.

Switching to transfers on port 388 is very simple:

1) replicate all of the request lines you have in your ~ldm/etc/ldmd.conf file
2) comment out one set of those request lines
3) modify the other set of request lines and remove the ':8080' form the 
upstream
   machine name portion of the request
4) stop and restart your LDM
5) do an 'ldmadmin tail' to look at the LDM log file to make sure that you did
   not introduce any typos in step 3)

> Thanks.

I think we are making good progress!

Cheers,

Tom
