[mapserver-users] Controling the amount of concurrent GetMap requests

[Mark Korver]

I would think that the thinking here is that a server only scales well
to some number of concurrent requests.  That beyond that number, all
requests suffer.  In this case it's better to queue the requests
rather than try to process them, meaning queuing improves performance
overall.
