I did some benchmarking on BlobFuse2 vs NFS vs azcopy on Azure for a CT imaging reconstruction a year back or so. As I remember it, it was not clear if Fuse (copy on demand) or azcopy (copy all necessary data before starting the workload) was the winner. The use case and specific application access pattern really mattered A LOT: * Reading full files favored azcopy (even if reading parts just when they were needed). * If the application closed and opened each file multiple times it favored azcopy. * If only a small part of many files were read, it favored fuse

Also, the 3rd party library we were calling to do the reconstruction had a limit in the number of threads reading in parallell when preloading projection image data (optimized for what was reasonable on local storage) so that favored azcopy.

Don’t remember that NFS ever came out ahead.

So, benchmark, benchmark, benchmark and see what possibilities you have in adapting the preloading behavior before choosing.
