In the function purple_util_write_data_to_file_absolute (libpurple/util.c) it does fflush and fsync.

This function is called to save prefs.xml and this file is saved too much time (every time you move pidgin window!). To get worse, I guess this function is called from the main thread, so if the system is under heavy I/O load o have a bad response time from a network drive (NFS) pindgin interface gets unusable for a while (30 seconds or more).

So there are varios solutions:

  1. Saving less times prefs.xml (only on exit pidgin or prefs saved by the user, for example)
  2. Launching this task in a separate thread on the background.
  3. Not flushing the contents? I supposse this can be dangerous, but i'm not sure.

Maybe just adding an "importance" parameter to the save function to avoid calling sync for frivolous changes would be good enough?...

We have bumped the Glib version so we can use GIO now and this is a good place to do so.

This ticket is too old and too vague. Closing because I don't know what it means for this ticket to be done.
