参数-T
是设置时序，数字越高，速度越快

往往选择合适参数的时间超过了所需优化的扫描时间。因此，Nmap 提供了一些简单的方法，使用 6 个时间模板，使用时采用-T 选项及数字(0 - 5) 或名称。模板名称有 paranoid (0)、 sneaky (1)、polite (2)、normal(3)、 aggressive (4)和 insane (5)。前两种模式用于 IDS 躲避，Polite 模式降低了扫描速度以使用更少的带宽和目标主机资源。默认模式为 Normal，因此-T3 实际上是未做任何优化。Aggressive 模式假设用户具有合适及可靠的网络从而加速扫描。Insane 模式假设用户具有特别快的网络或者愿意为获得速度而牺牲准确性。
