Solid neighbourhood-bakery energy. Trustworthy and warm.
Summary
Meta is renewing its commitment to jemalloc, a high-performance memory allocator that has been a foundational component in its software infrastructure. The article compares building software to constructing a skyscraper, emphasizing that while users see the final product, critical foundational components like jemalloc provide stability and performance. Meta recognizes jemalloc's long-term benefits in adapting to hardware and software changes, and aims to reduce maintenance needs while continuing to leverage its performance advantages for reliable infrastructure.
Key quotes
· 3 pulledBuilding a software system is a lot like building a skyscraper: The product everyone sees is the top, but the part that keeps it from falling over is the foundation buried in the dirt and the scaffolding hidden from sight.
jemalloc, the high performance memory allocator, has consistently been a highly-leveraged component within our software stack, adapting over time to changes in underlying hardware and upper-layer software.
Alongside the Linux kernel and the compilers, it has delivered long-term benefits to Meta, contributing to a reliable and performant infrastructure.
