Sorry, I should have been more clear.  When I asked if FreeBSD and&#x2F;or Linux could keep up, I was referring to the forwarding rates across four 1 GbE interfaces, like what the higher end SSGs came with. I certainly didn&#x27;t mean to imply that an x86 BSD box could perform right up there with a QFX10000, for example.<p>Now that I&#x27;m thinking about it, though, Arista runs a Linux kernel on their switches. Or they did anyways, the last time I was out there being briefed; it was a Fedora Core 3 install (yes, it&#x27;s been a few years), if memory serves, so it must be possible anyways. No idea if they&#x27;re still doing that but, at the very least, they were at some point.
