- Here is what I used:
-
- echo 'esp_ss1_esp0sync?W 1' | adb -w /vmunix
-
- I'm running a Sun 4/60 that we got in November of 1989, so
- it is one of the first ones and has not had any upgrades.
- I can get disk transfer speeds of well over 1M/sec, upwards
- of 1.8M/sec when reading the raw disk device, so I don't
- think going sync scsi hurts it at all. I haven't tried
- shutting sync scsi off and doing the same timing tests
- so I don't know how much of a difference itmakes.
