Performance Has Layers
Oxide Computer, Thursday, June 18th, 2026
Oxide explains how owning the full stack enables coordinated networking performance gains like jumbo frames.
Authored by Steve Karam of Product Assurance, this technical post argues that Oxide's vertically integrated hardware and software stack lets it optimize performance across many layers at once. It details recent networking work, including raising MTU from 1500 to 8500 bytes for up to a 4x improvement on external traffic, and achieving IPv6 throughput parity with IPv4.
A single user-facing toggle required synchronized changes across the virtual NIC, OPTE data path, kernel drivers, and control plane. The piece also covers CPU placement and flow parallelism, while cautioning that jumbo frames are not a universal performance fix.
