Hi,
has anybody compared the performance of UML's built-in blockdevice, NetworkBlockDevices, ATAoverEthernet, yet?
I don't know how UML's blockdevice works, but i know how NBD works. The kernel sends multiple requests to the NBD server, and receives the responses asap. The worse case for UML's block-device would be, if the UML-blockdevice would perform each read/write operation one after another. If it does that, it could be optimized by using a asynchronious queue/message-based operation like NBD.
Thx Sven
