Hi,
I have uncapped the docker container and created a profile with the old version, the new version and also the new version using the --azureblob-memory-pool-use-mmap flag.
I have also done a cpuprofile if that can be of any help.
It does not look like --azureblob-memory-pool-use-mmap helped at all.
Let me know if you need me to try something else.
