我的硬盘速度不对头:(太快了)
我的硬盘速度不对头:我用# hdparm -tT /dev/hda/dev/sda:
Timing buffer-cache reads: 128 MB in 1.25seconds =160.07 MB/sec
Timing buffered disk reads: 64 MB in 1.66 seconds = 38.55 MB/sec
有这么快吗? 正常,第一个是从硬盘自带的cache读进内存缓冲的,当然快
第二个是从硬盘直接读进内存,当然没那么快
我打开了DMA100,第二项是40.5MB/sec左右 内存是DDR吧 hehe, mine
/dev/hda:
Timing buffer-cache reads: 128 MB in0.35 seconds =365.71 MB/sec
Timing buffered disk reads:64 MB in3.26 seconds = 19.63 MB/sec
mine is a laptop disk, so real disk read speed is slow. but my ddr seems to be much faster than yours DDR怎么快这么多?还真是Double Speed hehe, true ddr. 我的酷鱼7200.7 DDR333,打开ATA100 测试64M是57 MB/sec
不知道X70(ATA133)是多少? 厉害 yes, my 15k rpm scsi disk can also get this number. but that is too expensive for home desktop use. 我的酷鱼7200.7 DDR333,打开ATA100 测试64M是57 MB/sec

这么快!我的酷鱼4只有40多一点。看来西捷要翻身了:mrgreen: 主要是7200.7 单堞80G的,而且内部传输率标称是58M/sec,说明linux的磁盘性能还是比windows好的,windows无论如何都达不到这个“理论速度”。 since windoze is not an open source one, so can not compare the software overhead between them. unbelievable mine
Timing buffer-cache reads: 128 MB in0.40 seconds =319.71 MB/sec
Timing buffered disk reads:64 MB in1.45 seconds = 44.16 MB/sec 大家的都差不多,所以就是正常的了。 :mrgreen:
