I noticed that the cp (copy) command is extremely slow on my system (-current). On average 'cp' copy rate is somewhere around 100kB/sec, while when I tried 'dd' (with bs=64k) the rate jumped to around 2-3MB/sec. Even at this rate, it is nowhere close to the perfomance I'd expect from the Fast UW SCSI system. The test file size is 100MB. The copy is done using both 2 drives and 1 drive. Is this to be expected? My system config: dual PII-266/512k 512MB RAM Adaptec 2940UW with IBM 4.1GB UW drives Kingson
