Yes, local deep storage, to a disk drive. The "atomic" update yes, which was enabled last year, made it 20x slower. You can still do the atomic update, but need to use the Buffered stream, not FilterOutput stream. It is not the fsync, it is the FilterOutputStream. This doesn't use buffers, is pushing a byte at a time? The change (almost certainly) is merely to use, a buffered output stream, need not remove the Atomic fixes for corruption issues. Thx again!
