Hey all,

rzs pointed me to a in interesting pdf document that does a simple benchmark of corba, dbus and dcop.

http://eleceng.dit.ie/frank/rpc/CORBAGnomeDBUSPerformanceAnalysis.pdf

According to those results dcop is 18 times faster.

6 times, since 18 is CORBA compared to DBus. Anyway this paper is *really* old (Slackware 10.2 had 2.4.31 kernel and was released on September 2005), so D-Bus developers have had plenty of time to make remote calls more efficient by caching, as suggested by the paper (but I don't know if they actually did this, or even if it is relevant to dbus itself or another layer).
