Issue Summary

In my company, we have a self-hosted instance of cal.com. But
The server is taking 20+ seconds to sync with an ICS feed.

Steps to Reproduce

1. Went to https://cal.mydomain.co/myuser/meeting?user=myuser&duration=25&overlayCalendar=true

It's super slow to show the calendar. The question is: Is this a normal behaviour? Or it is maybe a bug.
Or it can be related to some configuration items.

Actual Results

• Slow answer from the server.

Expected Results

• Maybe some improvements in the performance.

Technical details

• We are using the v6.2.0 version on the server.
• Docker compose to deploy.

Evidence

The test is basically to open the calendar url and we can see this behaviour.

During a test, we can see it's using a complete cpu in the process.
