我没有Knoppix LiveCD -a1024是什么意思?这个好像有问题
-a is to get or set the readahead buffer of your hard disk, default value is 256 kbytes. -a1024 increase it to 1024kbytes, in other words, increase your readahead buffer.
You can do a simply benchmark. You can compare the results before and after the change by;
hdparm -tT /dev/hda
If you don't have Knoppix, then you should download one. It is very very useful. Sometimes, it may help you to rescue your system. Don't tell me you do not know what is Knoppix. |
