Greg Pendlebury commented on SOLR-8955:
---------------------------------------

I like the idea, but maybe it should be configurable? If the master has 
multiple NICs than hard coding an arbitrary limit because two unrelated slaves 
from different network interfaces are both online would actually be more of a 
hindrance than an improvement.

> ReplicationHandler should throttle across all requests instead of for each 
> client

> SOLR-6485 added the ability to throttle the speed of replication but the 
> implementation rate limits each request. So e.g. the maxWriteMBPerSec is 1 
> and 5 slaves request full replication then the effective transfer rate from 
> the master is 5 MB/second which is not what is often desired.
> I propose to make the rate limit global (across all replication requests) 
> instead.
