The mailing list for listmasters using Sympa

[Adam Bernstein <address@concealed>]

Quick question for the Sympa folks, unless anyone else has gotten this 
working:

Largely in response to the exact slowdown mentioned below when enabling 
the merge_feature, we're working on spreading the sending load over more 
servers. The only document I can find is this one:
  http://www.sympa.org/manual/server_architecture_for_big_services

It's rather old, but still I think mostly relevant, and I'm thinking 
that moving bulk.pl onto a different server is most likely our best 
option. (We could just split the MTA by using relay hosts, but I'd 
rather go further.) And I want to confirm one thing: We can run bulk.pl 
at the same time on *multiple* servers, yes? There won't be any 
contention or locking issues or duplicated sends or anything?

I believe the fact that multiple bulk.pl child processes can run on the 
same server means the answer is yes, but just want to be sure.

Thanks!
