Sorry, but I did miscalculate something. 8KB seems to be a more
accurate value. But the old Atlas II really needs only 4K IO
chunk.
Results looks like the following:
Atlas II DDRS DGVS (sent to me by Marc SHAEFER)
4KB 9.5 MB/s 7.2 MB/s 9.0 MB/s
8KB 9.6 MB/s 12.2 MB/s ?? (about 17 MB/s sustaint)
Sorry for the wrong infos.
Gerard.
