Minimizing CPU Utilization of audisp Plugin

Hi, I'm currently working on a Python audisp plugin. My main routine looks like this: if __name__ == '__main__': try: ... aup = auparse.AuParser(auparse.AUSOURCE_FEED) aup.add_callback(process_event, None) while True: for _ in fileinput.input(): aup.feed(_) except: ... While profiling my plugin, I noticed that 95% + of the CPU time used by my plugin is used in fileinput.input(), waiting/reading from input Is there any way to lower this or preferred way to poll/read?
