perfSONAR User Q&A and Other Discussion

Hi Loren;

I am going to cross post this answer to performance-node-users.  The 
list is more geared toward the performance toolkit, and is located here 
if you are interested in joining:

How soon after bringing up the node did you configure?  The cache runs 
once an hour so it may not have kicked off yet.  If by the time you are 
reading this it still hasn't run, try to manually start it (it may take 
a minute or two to finish and there will be some output produced):

  sudo /usr/local/bin/cache.pl --verbose

Also, the cron entry should be here for reference:

/etc/cron.d/gls_cache

If that is not there there may be an installation problem.

Whats the load on the box look like?  The web stuff is pretty simple 
html so it *shouldn't* take a long time, but perhaps something else is 
hogging the system.

Thanks;
