Hello,

It depends on what kind of requests and responses are provoked by these tools. An high amount of data and/or connections may slow down certain network elements. For example my cheap D-Link router doesn't like a lot of concurrent connections (but has no problem with a single connection with a lot of bandwith usage). ZyWALL has a similar problem but only if QoS is enabled.

The best way would be to reproduce the problem by running the scanning utilities and analyzing the network traffic with a tool like Wireshark or tcpdump. If you see a slowdown, you might be able to determine the cause for this.
