 The command that may impact performance briefly and should not be used during heavy traffic times of day is fw tab -t connections. This command displays all the entries in the connections table, which can be very large and consume a lot of CPU resources. The other commands are less intensive and can be used safely. The command fw tab -t connections -s displays only the statistics of the connections table, such as number of entries, peak size, etc. The command fw tab -t connections -c clears all the entries in the connections table. The command fw tab -t connections -f displays only the entries that match a filter expression. References: [fw tab Command]
