This should be titled "how I learned to stop worrying about memory fragmentation and love jemalloc."

On a slightly more serious note, jemalloc is a pretty incredible piece of systems software. If you're experiencing issues with memory fragmentation or lock contention in malloc(3) it's definitely worth looking at.

Looks like there's also a Redis 2.2-jemalloc branch. Good to know.

You're right, jemalloc looks really good: After 24 hours of uptime, and 11592695 commands processed, the fragmentation is still 1.02 Thumbs up!
