[DGD] DGD/MP & OpenMosix revisited?

[Stephen Schmidt]

I hesitate to venture into a discussion which seems likely to get
technical, but I'll confine myself to asking questions and idly
speculating. Ignore the idle speculation if it goes off the track.

How are your servers going to connected to one another? If you
are relying on some kind of Internet connection between two
servers, couldn't this get awfully slow, waiting for requests
to come back from a remote server? The advantage to the "shard"
system isn't so much that it reduces storage, but that it
reduces the need for interprocess communication.

If your servers are all in the same lab somewhere and can
communicate at speeds resembling instant, then this might get
more attractive. I'd still worry about getting a bottleneck
at a server with some particularly frequently accessed object,
however.
