So yes, it could still use the JBM log ... you wouldn't see much performance benefit since the bottleneck will be the network.

I'd be surprised if the bottleneck is the network if the disk is just a normal disk. Standard network is 1 Gbit these days, but most disks write at around 30-80 MB/s = maybe 200 Mbits per sec.

If you're using a SAN with a load of disks in it, and parallel writing over those, then yes you could exceed write speeds > 1Gbit. (I'm looking forward to our new JMS lab to test this out).

Currently IIRC we've tested JBM writing records transactionally up to about 50MBytes/sec = 400 Mbits/sec on a cheap(ish) SCSI disk (dell workstation).
