There is only one call besides establishing the connection to the screen server that is time consuming because it involves opening and reading a configuration file. FLTK opens a preferences file that tells it if the preview in the file chooser should be enabled. Check if removing this call will improve performance. All other overhead probably comes from the operating system. Do you have a way to measure performance of individual functions? It would be great to see where this time is wasted.
