# Does the NetSenX agent slow down our servers?

It is designed not to, and the safest way to avoid any load on a server is not to install it there at all: one agent on a host connected to a mirror port watches the whole segment without touching the servers on it. A mirror port copies traffic inside the switch, so the monitored servers do not process anything extra, and the network path itself is not changed: the sensor only receives a copy. When you do install the agent on a server, it reads connection metadata and a few protocol fields, such as timing, volume, destinations, DNS answers and, where packets are captured, the TLS handshake. It never decrypts traffic and does not proxy or block connections. As with any new software on a busy server, watch its resource use for the first days, and pilot on a less critical host first. Ask NetSenX support before deploying on very high-traffic links.
