We've installed Moodle on AWS using a Bitnami build and it's all performing well until one of two scenarios.
1) We create a new user
2) A user completes a test
When these occur the page takes an age to load and eventually completes. Both of these actions trigger the sending of an email so I'm wondering if it is related to that. Our email is on Office 365 so we've set that up as smtp.office365.com:587 for the server name on TLS. All other settings are as default.
Has anyone else experienced this issue?
