[Opensim-users] Slow handling of POST -

[Justin Clark-Casey]

Fetch times of 1068560ms (which is more than 15 minutes!) are pathological - something is wrong.

In the first case I would suspect an issue with the connection to the OSGrid inventory service.  Either it is being 
overloaded (OSGrid actually runs multiple copies of the ROBUST inventory service and load-balances between them using 
Nginx, but perhaps the limits are being hit), things are being massive lagged because of lots of requests hitting the 
.net default connection limit, as Melanie discussed, or you have a network issue.

However, I'm a little surprised that the OSGrid Inventory Service request within FetchInventoryDescendents2 isn't making 
it's own complaint about a long request.  The log message you're seeing does cover the whole of the CAPs call so I 
suppose there is some chance there's some other cause, though it is a pretty simple capability.

If you want to see if viewers are doing a lot of inventory fetches, then you can try the command "debug http 3" on the 
simulator console.  This will show every incoming http request from viewers (and other simulators) and the HTTP URI they 
are hitting.  Very recent code also has levels 4 and 5 which will log a snippet of the incoming request and the entire 
request, though you probably don't want to use them for any length of time.
