What Hacker News says

All these concerns are critical, and this is why I spent 6 months to build OPIC malloc prototype. I surveyed a lot on state of the art malloc implementations, as well as some POC papers. The model I implemented is similar to scalloc and supermalloc. I did a simple benchmark, the performance is identical to jemalloc. That's seems good enough for me for now. OPIC has potential to use even faster concurrency model dropping atomic implementation and move to urcu (user space rcu). However, this is not very necessary for a serialization focused malloc. The detail of how I implemented this malloc will be discussed in later post. Reference. https://github.com/cksystemsgroup/scalloc https://github.com/kuszmaul/SuperMalloc
