Adjust HTTP request timeouts for slow networks
```
~$ subscan scan -d example.com -t 120
```

Use a proxy server to bypass anti-bot systems

~$ subscan scan -d example.com -t 120 --proxy 'http://my.prox:4444'

Increase concurrency to speed up the scan
```
~$ subscan scan -d example.com -c 10
```

Fine-tune IP address resolver component according to your network

~$ subscan scan -d example.com --resolver-timeout 1 --resolver-concurrency 100

Disable the IP resolution process

~$ subscan scan -d example.com --disable-ip-resolve

Customize the scan by filtering modules

# skip the commoncrawl and google modules during the scan
~$ subscan scan -d example.com --skips=commoncrawl,google

# run only the virustotal module
~$ subscan scan -d example.com --modules=virustotal

If a module is included in both the --skips and --modules arguments, it will be skipped and not executed
