[systemd-devel] sd-bus vs gdbus on dbus-daemon

[Umut Tezduyar Lindskog]

Hi,

We [1] have noticed that there could be up to %50 performance gain on
using sd-bus over gdbus on dbus-daemon. For this reason, we have high
interest in using sd-bus. What are the plans in terms of making sd-bus
API public?

Details of the test [2]:

gdbus.c
  - g_dbus_proxy_new_for_bus_sync()
  - 50 x g_dbus_proxy_call_sync()

sdbus.c
  - sd_bus_open_system()
  - 50 x sd_bus_get_property()

Two applications are run with "ltrace", "perf stat -e cycles", "time"
and the results are compared.

[1] - Most of the work is done by Jonatan Nilsson, I have added minor points.
