## Significantly reduced median spinup time for cron jobs

Recent improvements to build caching have significantly reduced the median spinup time for Render [cron jobs](/content/docs/cronjobs/index.html)—especially cron jobs that run multiple times per hour.

Previously, each run of a cron job took approximately 20 seconds to spin up in the median case. Now, cron jobs that use the new build caching strategy often spin up in 5 seconds or less.

**To take advantage of this speedup, make sure you've triggered at least one new build for your cron job since February 1, 2025.** You can manually trigger a build from the cron job's **Builds** page in the [Render Dashboard](https://dashboard.render.com/):
