General questions

Hi,
My Matomo is monitored with Prometheus BlackBox Exporter, homepage response time is around 200 ms except every night at 1 AM where I have a peak to 10 seconds…

What can explain this peak?
(archive cron is planned every 5 minutes)

Thanks

Can I disable or re-schedule some tasks ?
