This article mainly introduces the Linux 3.0 file system EXT4 and Btrfs test comparison of the example analysis, the article is very detailed, has a certain reference value, interested friends must read it!

EXT4 file system may be familiar to everyone, now popular ubuntu 11.04 and Fedora15 are used by default. EXT4,EXT4 is the fourth-generation extended file system of Linux and the successor version of EXT3.

Btrfs is called the next generation Linux file system. In recent years, ext2/3 has encountered more and more scalability problems. While looking forward to ext4, people have discovered btrfs. It is said that it adopts a lot of advanced file system design, which not only solves the scalability problem of ext2/3, but also makes people see many other features of the next generation file system. Feora has announced that the default file system in Fedora 16 is Btrfs.

Now let's take a look at the results of phoronix.com 's test of these two file systems. I won't say much about the hardware. Phoronix.com uses two computers from different manufacturers to install ubuntu 11.04 Linux kernel version 3.0, which installs 32-bit and 64-bit systems respectively. Take a look at the test results:

The test uses apache static website service, in terms of file reading speed, on high-end notebook computers using Sandy Bridge CPU and Intel XMUI 25 SSD hard drives, BTRFS is much faster than EXT4, and the processing speed of BTRFS is 24% higher than that of EXT4. But in another low-end laptop Pentium M+HDD hard disk configuration, the processing speed of the two file systems is basically the same, which may be due to the limitation of CPU bottleneck.
