    Why is this on the HN front page? Is there something particularly noteworthy about this release?

      jemalloc is something you should be aware of if you do software for a living

        Why? Writing a memory allocator is quite simple, and I'd argue that _everyone_ should write one from scratch for any kind of high performance application. It's also trivial to outperform general purpose allocators that have to satisfy countless constraints. I've written numerous special purpose mallocs that are a) both provably (formally) safer than the standard armada and b) significantly faster (>10x throughput).

          Writing an allocator is simple, you’re correct, but writing an allocator that doesn’t suck is not simple.
