I have few query regarding the run time performance of qt embedded.
Which gives better performance.?
1) IPC using DBUS
2) using threading
3) or using Socket or Shared Memory.

I am using DBus and passing data over two application mainly Messages. I am suffering with Slow system response.
I am using 200Mhz processor mainly for Qt only, but qt Processevent() take almost 30ms to process events from another process using dbus.

Does dbus has certain limitation when use with Qt?
Does anybody has face same kind of problem when Using IPC with Qt.
