Parameter adjustment, solve the problem of packet loss

There are many reasons for packet loss, roughly divided into two.

1. network problems (solution: 1. switch to a better network 2. modify the -t timeout time)
2. cpu processing super link performance is insufficient (solution: reduce the number of concurrent)

• Extranet scan, not missing a port
  • Modify thread parameters -c Calculation formula: Number of current CPU logical cores * 100
  • Example: Current CPU logical core is 4 cores Parameter is blackwater -i github.com -c 400 -p 1-65535
• Intranet scan, not missing a port
  • Modify thread parameters -c Calculation formula: Number of current CPU logical cores * 250
  • Example: Current CPU logical core is 4 cores Parameter is blackwater -i 192.168.88.11 -c 1000 -p 1-65535
