The results are consistent with previous runs. There is a degradation of read speed (MB/s) over time. The longer run scheduled August 6th, 2021 will provide a confirmation and help analyze the root cause. It may be cause by the increasing number of images: they are all mapped and mounted (200 towards the end) even though only five of them are used for reading. analyze the results.Thousands of images (smaller images) were mapped on a single machine and did not cause problem (that was a few months ago) but the focus was not on read speed at the time.
