描述

Currently, one of the largest consumers of memory is the metrics datastore layers 'hdr histogram'. It consumes between 20 and 30MB of memory. It would be nice if when IPFS_LOW_MEM is set that this layer doesnt get added in, or gets slimmed down in some way.

研究方向
Investigate how IPFS LOW MEM is used elsewhere in the codebase (search for the environment variable). Locate the initialization of the metrics datastore layer that includes the hdr histogram, likely in the metrics package. Modify the code to conditionally disable or slim down that layer when IPFS LOW MEM is set. Check comments for any prior attempts and clarify with maintainers whether complete removal or reduction is preferred.
