Re: High memory usage in provider server

[Claudio Cuqui <claudio@c3systems.com.br>]

I think the real question here is: what replication strategy will make 
supplier server consume less memory: Syncrepl - pushing records from 
supplier to consumers ? Consumers pulling records from supplier via 
syncrepl ? Delta-syncrepl pushing records from supplier to consumers ? 
Consumers pulling records from supplier via Delta-syncrepl ?
