DigitalOcean has upgraded its App Platform infrastructure to a new version of gVisor, which improves runtime performance and reduces the overhead of handling syscalls. The new systrap platform allows for more efficient interception of syscalls, resulting in improved performance for network-bound workloads. The company tested the new version with a minimal Node.js app and a WordPress app, achieving over twice the throughput on the Node.js app and over seven times the throughput on the WordPress app. However, some regressions were found, including incompatibilities with application behavior and issues with the platform itself, which were addressed through close collaboration with the gVisor team. The company took a slow and canary-based approach to rolling out the change across its fleet of clusters, ensuring minimal disruption to users.
