Subject: Re: [Oscar-users] How to run services/daemon on Cluster.
It probably is a bit on the obvious side, but the easiest way
to
provide more bandwith for any given service is to put it on its
own
machine. That is probably the best you can do without
specialized
software but it can be complicated to set up.
That being
said, Oscar can't help you with this as David mentioned
indirectly. As
far as server set ups go, it would give you almost
exactly what you have now
and don't seem to want, which is all
services running on one
machine.
Sorry we couldn't be more help.
