Comparison of speeds between nmap and naabu: Why is nmap faster? #1519
Description
Why is it that a simple full-port SYN half-connection scan on the client side is twice as fast as Naabu in nmap? Is it because my parameter settings are incorrect, or is it simply that nmap cannot match its speed?
The configuration parameters when using nmap are as follows
-sS -Pn -p T:0-65535 --source-port 58915 --max-retries 0 --min-rate 20000 --max-rate 20000 -n -v -T3 --open --stats-every 5s --min-hostgroup 100 --max-hostgroup 100
When using Naabu, the configuration parameters are as follows. The version of Naabu is 2.3.3.
ScanType: "s",
//OnResult: func(hr *result.HostResult) {
// log.Printf("host:%s:%s", hr.Host, hr.Ports)
//},
//Debug: false,
//Verbose: false,
//StatsInterval: 0,
