# Example configuration file for the S2SS server
#
# This example includes all valid configuration options for the server.
# Please note, that using all options at the same time does not really
# makes sense. The purpose of this example is to serve as a reference.
#
# The syntax of this file is similar to JSON.
# A detailed description of the format can be found here:

affinity = 0x02;					# Mask of cores the server should run on
							# This also maps the NIC interrupts to those cores!

priority = 50;						# Priority for the server tasks.
							# Usually the server is using a real-time FIFO

debug = 5;						# The level of verbosity for debug messages
							# Higher number => increased verbosity

stats = 3;						# The interval in seconds to print path statistics.
