本篇文章主要介绍了"Linux下各种主要文件系统的读写性能测试",主要涉及到Linux下各种主要文件系统的读写性能测试方面的内容,对于Linux下各种主要文件系统的读写性能测试感兴趣的同学可以参考一下。

1、不用说,tmpfs是最快的,呵呵   2、ext2   写测试:   CODE: 双击代码全选 1 2 3 4 5 6 7 debian:/mnt/sda1# time dd if=/dev/zero of=test bs=1024 count=100K 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 1.40192 seconds, 74.8 MB/s real  0m1.414s user  0m0.140s sys  0m0.230s   读测试:   CODE: 双击代码全选 1 2 3 4 debian:/mnt/sda1# time cat test > /dev/null real  0m2.084s user  0m0.000s sys  0m0.310s   3、ext3   (1)data=ordered   写测试:   CODE: 双击代码全选 1 2 3 4 5 6 7 debian:/mnt/sda1# time dd if=/dev/zero of=test bs=1024 count=100K 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 1.04712 seconds, 100 MB/s real  0m1.057s user  0m0.090s sys  0m0.580s   读测试:   CODE: 双击代码全选 1 2 3 4 debian:/mnt/sda1# time cat test > /dev/null real  0m1.429s user  0m0.020s sys  0m0.290s   (2)data=writeback   写测试:   CODE: 双击代码全选 1 2 3 4 5 6 7 debian:/mnt/sda1# time dd if=/dev/zero of=test bs=1024 count=100K 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 0.990267 seconds, 106 MB/s real  0m1.004s user  0m0.110s sys  0m0.470s   读测试:   CODE: 双击代码全选 1 2 3 4 debian:/mnt/sda1# time cat test > /dev/null real  0m1.339s user  0m0.010s sys  0m0.250s   (3)data=journal   写测试:   CODE: 双击代码全选 1 2 3 4 5 6 7 debian:/mnt/sda1# time dd if=/dev/zero of=test bs=1024 count=100K 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 6.45851 seconds, 16.2 MB/s real  0m6.470s user  0m0.080s sys  0m0.590s   读测试:   CODE: 双击代码全选 1 2 3 4 debian:/mnt/sda1# time cat test > /dev/null real  0m1.665s user  0m0.010s sys  0m0.220s   4、ReiserFS   写测试:   CODE: 双击代码全选 1 2 3 4 5 6 7 debian:/mnt/sda1# time dd if=/dev/zero of=test bs=1024 count=100K 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 1.13243 seconds, 92.6 MB/s real  0m1.153s user  0m0.040s sys  0m0.620s   读测试:   CODE: 双击代码全选 1 2 3 4 debian:/mnt/sda1# time cat test > /dev/null real  0m1.543s user  0m0.000s sys  0m0.240s   5、XFS   写测试:   CODE: 双击代码全选 1 2 3 4 5 6 7 debian:/mnt/sda1# time dd if=/dev/zero of=test bs=1024 count=100K 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 1.76025 seconds, 59.6 MB/s real  0m2.000s user  0m0.060s sys  0m0.470s   读测试:   CODE: 双击代码全选 1 2 3 4 debian:/mnt/sda1# time cat test > /dev/null real  0m2.203s user  0m0.010s sys  0m0.270s   6、JFS   写测试: CODE: 双击代码全选 1 2 3 4 5 6 7 debian:/mnt/sda1# time dd if=/dev/zero of=test bs=1024 count=100K 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 0.581869 seconds, 180 MB/s real  0m0.613s user  0m0.140s sys  0m0.250s   读测试: 双击代码全选 1 2 3 4 5 CODE: debian:/mnt/sda1# time cat test > /dev/null real  0m0.579s user  0m0.010s sys  0m0.350s   JFS文件系统还真快ext3文件系统下,如果设置为data=journal,效果要打不少折扣哦
