Chapter 13: Advanced Settings
Poll Offloading
Poll offloading is a feature that is available on certain hardware platforms and increases
throughput by distributing interface polling functions to another processing core. It is enabled
by default where available and should only be disabled for debugging purposes.
Default: Enabled
Number of polling cores
This is the number of processing cores used by poll offloading if it is enabled and functioning.
This setting should be left at the default value.
Default: 1
Pseudo Reassembly Settings
Max Connections
Packet re-assembly collects IP fragments into complete IP datagrams and, for TCP, reorders
segments so that they are processed in the correct order and also to keep track of potential
segment overlaps and to inform other subsystems of such overlaps. The associated settings limit
memory used by the re-assembly subsystem.
This setting specifies how many connections can use the re-assembly system at the same time. It
is expressed as a percentage of the total number of allowed connections. The minimum value is
1. The maximum value is 100.
Default: 80
Max Memory
This setting specifies how much memory that the re-assembly system can allocate to process
packets. It is expressed as a percentage of the total memory available. Minimum 1, Maximum
100.
Default: 3
Screen Saver Settings
Timeout
The time in seconds before NetDefendOS automatically enables its screen saver for a
NetDefendOS Software only installation. The screen saver will automatically adapt its activity to
the current CPU load of the system. During high loads, it will update once per second,
consuming a fraction of a percent of CPU load.
Default: 300 seconds (5 minutes)
