Re: Question about daos read bandwidth
The current DAOS does not have any cache, I think it’s probably because you are reading from data extent which has no data, in that case, DAOS will not transfer anything through the network, you might see higher bandwidth then the capability of network/storage.

Will daos have a cache for 128KB reads, or is there a prefetch operation? When I use spdk bdev for testing, I found that the bandwidth of DAOS sequential reads exceeds the bandwidth of SSD devices.
