To benchmark Chefs vs. Sous-Chefs vs. SFSRO

On the CDN machine (ring), run sfsrodb/populate.sh to create:
 rodb.rodb  (the encrypted content)
 rodb.rodb.kr (the key regression state)
 rodb.rodb.nokr (the sous chefs key state)

Copy rodb.rodb.nokr and rodb.rodb.kr to the key manager machine (snafu)
 Create a "testdir" and put rodb.rodb.nokr in it.
 Run the sfsrodb program on testdir.
 ./sfsrodb -d testdir -o rodb2.rodb -h snafu.lcs.mit.edu -s sfs_host_key  -g 0 -f 1
 This technically uses key regression, but with a chain of length 1.


For Sous-Chefs test:
 Run sfsrosd using publishfile rodb2.rodb and the rodb2.rodb.kr key file.
 trickle -d 100 -u 100 /home/fubob/src/build/build-O2/sfsrosd/sfsrosd -f sfsrosd_config -k rodb2.rodb.kr 
 
For Chefs test:
 Run sfsrosd using publishfile rodb2.rodb and the rodb.rodb.kr (!!) key file.
 In the Chefs test, we won't actually serve content from rodb2, but we'll answer
 GETKEY requests.
 trickle -d 100 -u 100 /home/fubob/src/build/build-O2/sfsrosd/sfsrosd -f sfsrosd_config -k rodb.rodb.kr 

On the client machine, set SFSROCD_NOKR=1 if testing Sous-Chefs.

For SFSRO, run the same experiment, but don't use a key manager and
don't encrypt during sfsrodb creation.
