1.6 Million IP Connections on FreeBSD

An anonymous reader writes "FreeBSD developer Terry Lambert, in a recent posting to the 'freebsd-hackers' mailing list, mentioned that he'd tuned a FreeBSD 4.4 box with 4GB of RAM to achieve 1,603,127 simultaneous IP connections, and goes on to say: 'As far as I know, I hold the single machine connection record for an x86 box.' This is an impressive achievement any way you look at it (though it begs the question of whether or not the box had any resources left to actually do anything with those connections...), and it speaks well of both FreeBSD's capabilities and Terry's skills and knowledge. I'm curious, though, if anyone has approached, matched, or exceeded that number elsewhere?"

theres no point in the mysql test on top of the ip test, it then becomes even moreso a pure kernel test (eg scheduler/vm....), plenty of which have been done.

But i do think that serving out 1k of html would make the test a bit more solid.

Id be interested, given this narrow field thats being tested on how linux would hold up under the same tweaking, and what tweaking exactly that would require as compared to the freebsd (yes its probably trivial, but im just curious).
