The site can take +30s to load, login actions can take upwards to 20 seconds to happen. Navigating around the site can also take 20-30s. Other times it will be quick, it is inconsistent.
I notice this more because I'm writing UI automated tests (which are not load tests and run one at a time). When the UI test is slow, interacting with the site in a separate session also is slow.... so not related to the testing.
Actions performed which don't have an API dependency seem to be fast when the general interaction with the site is slow. So perhaps related to API/DB.
Looking in Azure insights, slow performance results from API comms do appear to backup what I'm seeing as pictured below. Looking at SQL performance for the same time period, we're hardly utilising the DTUs.
