A LinkedIn post from Depot highlights significant performance gains in the company’s CI-focused microVMs, describing a reduction in cold-boot times from roughly 7–9 seconds to sub-second levels. The post details a series of kernel, systemd, and cloud-init optimizations, as well as custom initramfs work, that collectively reduce boot latency and improve determinism.

According to the post, Depot used Cloud Hypervisor on KVM and systematically removed unnecessary services, modules, and configuration probes, ultimately achieving median boot times around 0.6 seconds and P90 near 1.2 seconds. The narrative also notes remaining variance tied to OCI-backed root disks and indicates that further gains may be pursued via VM memory snapshot and restore capabilities.
For investors, the technical progress described suggests Depot is focused on deep infrastructure-level efficiency for its CI platform, which could translate into faster build cycles, higher throughput, and better resource utilization. Such improvements may enhance Depot’s competitive position versus other CI and infrastructure providers, particularly for latency-sensitive workloads and cost-conscious enterprise users.
If these optimizations are productized reliably at scale, Depot could see improved unit economics as each physical host supports more concurrent builds with reduced overhead per job. The emphasis on kernel and hypervisor tuning may also position the company as a differentiated player in developer tooling, appealing to customers that value low-level performance engineering and predictable CI runtimes.
