I don't know if the load really started dropping on (new)thelma
after you switched motherlode off to emo, or if it was heading down
because of me moving SGSU, UNL, and CU/CIRES (NOAA) off, but the
load average now looks manageable:

For the "files", here is a record of the load levels starting
at the time I started to move feeds off:

The key things I see from the uptime log are:

- number of downstream feeds has dropped
- number of upstream feed requests has increased: 17 -> 26 ?
- the number of processes in a WAIT state dropped: 28 -> 4

(new)thelma appears to be alot more responsive now which is a relief.

I am tempted to stop and restart (new)thelma to do the following:

- remove the two CRAFT requests that are not viable anymore
  (remove requests to 129.15.194.23[12])

- perhaps switch the CRAFT request to a single one from emo
  which is feeding from Purdue in a test mode

- remove the redundant feed of CONDUIT data from tgsv32

If I made the second two of these changes, the number of data requests
would drop by 13.  This could have a significant impact on the idle
time available to (new)thelma which is currently hovering at about 1%.

Thoughts?
