We've had a surprising amount of difficulty maintaining this over the years, since FreeBSD's NFSv4 implementation kind of sucked for a while, and it doesn't support mounting a memory partition (tmpfs). But you can trick it by mounting the memory partition using nullfs, and then nfsmount-ing that.

We used that memory-partition-over-network thing for a while, but actually switched to SSD-over-network because it was faster than the memory partition. I spoke with a FreeBSD maintainer about it and he said what we were doing was so unsupported/unoptimized that he wasn't surprised.

We run into weird FreeBSD edge cases pretty often where there are few people, if anyone, who can answer our questions. Sometimes I wish we'd gone with Linux, but after ten years the hassle of switching doesn't seem worth it. Thankfully 9.2-RELEASE has been pretty good to us.

Why even write the html to disk? 4chan flushes history so aggressively I'd think you could fit all the high-traffic stuff in memory.

if there's a power-blink and the posts get lost? Its 4chan.
