No, that's about right. You will have the i586-optimised copyin/copyout code, which makes the P5 faster (on this particular benchmark) than the P6. This is a P5/166 with 60ns ECC (_not_ EDO) DRAM, 512K cache, 430HX and conservative BIOS settings : bom:~>dd if=/dev/zero of=/dev/null bs=1m count=1000 1000+0 records in 1000+0 records out 1048576000 bytes transferred in 8.186862 secs (128080332 bytes/sec) As Bruce has observed, this makes for very healthy IDE performance, which is what this whole thread started with. > -Ken Stox -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
