Ubicloud runner benchmarks with premium routing explained

TechCompare publishes measurements from its own runner benchmark suite. The results come from the supplied published reports, while provider documentation supplies hardware mappings, prices, and available sizes. Scores from provider marketing pages aren't used as test results.

No. CoreMark is a CPU microbenchmark running one execution thread. A full build also depends on parallelism, memory, disk, dependencies, cache behavior, and queue time. This snapshot doesn't measure complete application builds or queue delays.

Each score is a geometric mean of that runner's own measurements. Disk combines sequential read/write MiB/s with random read/write IOPS converted to MiB/s using the 4 KiB operation size. Cache combines save and restore MiB/s from one backend. By default, each runner uses its highest verified score across tested cache and artifact backends. Hover or open details to see the backend, or select a specific backend type. Internet combines available download and upload Mbps, or uses the single recorded direction. Protocol 7 reports speeds from actual payload bytes and elapsed time, including transfers that reach the time limit. Older timeout records use recorded bytes divided by the nominal limit. These fixed formulas have no ranking reference or upper score limit, so adding a faster runner doesn't change existing scores. CPU keeps its measured CoreMark iterations per second.

A fixed runner's quoted minute rate is divided by its billed vCPU count. Prices are shown in USD and are list or overage rates before allowances and extras. RunJob publishes EUR consumed CPU rates, which are converted using the dated ECB reference rate shown on the page. Its original rate stays in the details, and memory charges are additional. GitHub uses private standard rates, and Namespace shows overage with prepaid equivalents.

CPU value is the measured single thread CoreMark score divided by the USD cost per vCPU per minute. More billed vCPUs don't multiply the measured score. EUR compute rates are converted before calculating value, so every provider is in one USD ranking. K means thousand and M means million. Optional disk, cache, and internet value columns use the same score divided by rate formula. These ratios don't measure full build performance or predict the final bill.

Some virtual machines expose only AMD EPYC or aarch64. The table uses a provider mapping where documentation identifies a family, labels that evidence, and leaves undisclosed model numbers unconfirmed. Similar benchmark scores aren't enough to identify a processor.

No. Internet transfers with a nonzero recorded byte count can supply a speed even if they reach the time limit. A blocked request or a timeout with no recorded bytes stays unscored. Disk uses verified sample medians with all four throughput components. The updated BuildPulse ARM disk result is included using its three completed samples, with the original counts in the details. Cache requires all three verified save and restore pairs. The table shows a dash when no score is available. Hover or open the row details to inspect the measurements.
