Hi,

Is there a way to calculate rsync max connection (i.e based on number of 
hosts, devices, object server workers etc)?

Some context: we have recently gone live with Swift 2.7.0 cluster (2 
regions, 6 hosts overall, each with 16 cores/32 threads and 4 drives). 
We have rsync max connections to 25 (which I think is being set by 
puppet-swift.., is the default value). We are seeing errors in the rsync 
log: 'max connections (25) reached'. I'd like to be able to say to the 
operations guys: set 'max connections to x, because <some rules for 
calculating it>'.


Cheers
