* 243 [12:56] roberto:~/.ncmdir> dd if=/dev/zero of=/dev/null bs=64k count=16000 : * 1048576000 bytes transferred in 16.094320 secs (65151930 bytes/sec) * 244 [13:10] roberto:~/.ncmdir> dd if=/dev/zero of=/dev/null bs=1m count=1000 : * 1048576000 bytes transferred in 19.304305 secs (54318247 bytes/sec) Ouch. That's horrible! Even a p P133 with 2.1.5 (i.e., without the fast copyin/out) can get 80MB/s on both.... By the way, does anyone have a K6 with an Apollo chipset? * K6-166 @ 2.5x 75 MHz on ASUS P55T2P4. I'm surprised as I got about 144 Mb/s * with my previous setup (P133 @ 2x 83 MHz). That's impressive. * CPU: AMD K6 (187.94-MHz 586-class CPU) * Origin = "AuthenticAMD" Id = 0x561 Stepping=1 * Features=0x8001bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8> Could it that the motherboard does not support all of K6's new features? (I heard you need a new BIOS for that if you have an older version of some motherboards.) Or maybe Mr. Kato will add them to his CPU-specific optimization code too. :) Satoshi
