is gtop1.0.5 really so sluggish?

[Ariel Burbaickij <Ariel Burbaickij mni fh-giessen de>]

Use fbsd 3.2 proccesor is Penthium II 400Mhz
Programm needed about 10 to 12 sec to wound up.
Is it expected behaviour?
Besides,
tried to maximiye the window got:
Gtk-CRITICAL ** : file gtkwidget.c:
line 1584(get_widget_map):
assertion 'GTK_WIDGET_WIDGET_VISIBLE==TRUE' failed
Afterwards window jumped babk to its previous size.
Any help?
As to the time the same amount approx is required by gedit.
Best Regards,
Ariel
