We are seeing delay in emails on the subscribed dashboards.
the dashboard are loading in within 1-3 mins but if we setup subscription say at 10AM, them mail is sent with a delay of ~0.5 to 1 hour.
When we send the dashboard manually after clicking on send now it works fine.
We have already checked below points:
CPU utilization of metabase pod is very less (less than 10%)
Memory utilization : ~5GB max
Version used: 0.46.7 - quite recent. [Latest 0.47 released few days back only]
Backend DB: postgres (as suggested per best practices)
Please let us know if you can tune anything from our end.
