This technical article details the author's investigation into poor TCP network performance on NetBSD systems, identifying VirtIO driver issues as the primary culprit. The author demonstrates how switching to E1000 network drivers and applying specific tuning parameters significantly improves throughput. The findings reveal that NetBSD can achieve competitive network speeds when properly configured.
Background
BSD operating systems are known for their robust networking stacks, but performance can vary significantly based on hardware drivers and configuration. Virtualization environments often use VirtIO for improved I/O performance, but driver implementations differ across BSD variants.
