With the CPU overhead imposed in checksum of blocks by ZFS, on a large sequential write test, the CPU was heavily loaded in a test that I ran. By turning off the checksum, the CPU load was greatly reduced. Obviously, this caused a tradeoff in reliability for CPU cycles.
Would the logic behind ZFS take full advantage of a heavily multicored system, such as on the Sun Niagara platform? Would it utilize of the 32 concurrent threads for generating its checksums? Has anyone compared ZFS on a Sun Tx000, to that of a 2-4 thread x64 machine?
