Short answer: updates should propagate in about a minute, and can be near-instant with streaming; some SDKs poll roughly every 60 seconds by default. There isn’t a region-specific delay documented—latency depends on your SDK and whether you use streaming (SSE) via the Proxy. - Default behavior: most non-JS SDKs poll and fetch new features about every ~60 seconds (configurable). [[API latency](https://github.com/growthbook/growthbook/issues/1457)] - Fastest path: JavaScript-based SDKs with streaming (SSE) via the GrowthBook Proxy receive updates almost instantly (under a second) when features/experiments are changed. [[API latency](https://github.com/growthbook/growthbook/issues/1457)] - In general usage, updates “should happen after roughly a minute” unless using streaming. [[API latency](https://github.com/growthbook/growthbook/issues/1457)] - Dashboard toggles going live are “almost instant,” assuming publish is completed; any remaining delay is typically SDK cache/polling. [[Delay to live](https://linen.growthbook.io/t/13157170/hello-i-have-a-general-question-after-enabling-an-experiment); [API latency](https://github.com/growthbook/growthbook/issues/1457)] So for Southeast Asia, Latin America, Europe, or elsewhere: expect near-instant with JS+Proxy streaming, or roughly up to a minute with default polling SDKs. If you’re seeing longer delays, check SDK caching/poll intervals or enable streaming. [[API latency](https://github.com/growthbook/growthbook/issues/1457)]
