Hi,<br><br>For me, the message speed is important and 4.7ms per message is too slow, because :<br> - 100ms is the max reaction time for the user<br> - I have several applications interconnected together through an IPC (will be DBus or another)<br>  - that can send several messages in the same time<br><br>In my system, there are situations where several applications send several messages in the same time, and it cannot fit the 100ms.<br><br>That is why I would be interested by a quicker direct DBus.<br> <br>Jerome<br><br><br><div class="gmail_quote">2008/10/31 Simon McVittie <span dir="ltr"><<a href="mailto:simon.mcvittie@collabora.co.uk">simon.mcvittie@collabora.co.uk</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="Ih2E3d">On Fri, 31 Oct 2008 at 17:23:16 +0200, Alberto Mardegan wrote:<br> > I was not especially thinking of the desktop, but rather to the Maemo platform<br> > and Telepathy specifically: for instance, telepathy connection managers<br> > typically communicate with 1-2 processes only<br> <br> </div>... for very large values of "2" that include Mission Control, the<br> presence UI, the chat UI, the VoIP UI, and future collaborative stuff.<br> Sorry, Telepathy is not a good example here!<br> <div class="Ih2E3d"><br> > Yes, that's true.
