During this I found out that Redis re-implements <code>malloc</code> for its own use case, and further that Redis uses <code>jemalloc</code> instead of <code>malloc</code>.</p> <p>I got curious as to why? What <code>jemalloc</code> was, what it does, and how it improves over our all-knowing classic <code>malloc</code>.</p>
