[nsp] slb predictor

[Daniel Medina]

 Are there any important differences between using roundrobin and
leastconns as slb predictors?
                                                                                         
 I was assuming that using leastconns would be preferred in all cases,
as reals coming into a serverfarm would fill up more quickly.  What's
the advantage of roundrobin?
                                                                                         
 Cisco doesn't seem to offer any documentation about this (beyond
"leastconns...directs network connections to the server with the fewest
connections.")
