There is no "standard" speed as it all depends on many factors,
especially the system load and load on the bus itself. You can always
use peer-to-peer connections if you need lowest latency but then
you'll giving up on the security policy implemented by the
broker/daemon, easy discoverability etc.

Depends on what you mean by "data streaming" exactly. If you mean
pub/sub model where you subscribe to some events and then get notified
for them, then yes.

OTOH if you mean multimedia content (e.g audio and video), you **can**
(as long as all of your messages are less than 128MiB) but it's not a
good idea, especially if you're communicating through the broker (the
usual/default scenario). Typically, D-Bus is used for control and
metadata while streaming happens out-of-band. You'd use D-Bus to
communicate the metadata about the stream channel between the
processes involved (e.g the UDP port used).
