I wasn't sure if C1000K sounded better ;) I'm 90% finished writing up my findings as Part 3 to my comet series on www.metabrew.com - it turns out that my client process (C+libevent with my patch) that opens 1M connections takes 2.1GB resident once all 1M connections are established. With my (slightly uninformed) tcp/kernel tuning to make it possible, the box is actually consuming close to 10GB though. So it looks like 8GB is consumed by the kernel/tcp stack to maintain the connections, which seems a bit high - but I have no basis for comparison.
