1885	cloud backend: redundant reads of chunks from cloud when downloading large MDMF file	davidsarah		"I uploaded a 7.7 MiB video as an MDMF file using the cloud backend on S3 (as of [https://github.com/davidsarah/tahoe-lafs/commit/022796fb7813c2f42d668a0ee3de9abae869deb5 1819-cloud-merge/022796fb]), and then downloaded it. From {{{flogtool tail}}}ing the storage server, I saw that it was reading the same chunks multiple times during the download. That suggests that the chunk cache is not operating well enough.

The file was being downloaded by playing it as a video in Chromium; I don't think that makes a difference."	defect	new	normal	1.11.0	code-storage	1.9.2		cloud-backend cache download performance mdmf
