Hello, When you say same hardware, is it the exact same memory, CPU, disk, .etc? Are you running any extra applications on your Linux system such as a network monitor or a network IDS? What about a local firewall logging all connections in/out? Also, are you running the same exact scan configurations? You mention 70/30 hosts/checks, but I would be curious if you are also comparing the same scan configurations such as thorough checks. Lastly, I would also compare any process loads on the FreeBSD system to the Linux system. We've been very wary at Tenable to produce any sort of "this OS is faster than this OS" type of guidelines because there are many variables to consider.
