I have in the past two weeks noticed that requests for time ranges of more than a few months of sentinel 2 data take much longer than they used to, regardless of whether requesting a small field parcel or a larger region, and whether directly using the Sentinel hub library or using eo-learn
I looked into the inner-workings and find that most of the individual requests (for a single image on a single day) are really fast (less than a second - and are run in parallel), while others take hundreds of seconds. These requests are fast when executed alone. These requests should bring me nowhere near my rate limits and there is no evidence of rate limited requests in the dashboard.
The effect is seen regardless of the spatial location or extent, and regardless of the time range requested as long as it is over a few months.
I have never experienced this problem before and have not changed or updated any of my software (i.e. sentinel hub library), and it occurs on different computers with different operating systems, python versions and library versions.
I hope this can be resolved ass soon as possible because this delay makes my normal workflow impossible.
