XFS 3.0.0 删除测试+压缩解压测试

yourfriend · 发表于 2009-6-23 00:19:32

ext3 大张旗鼓的升级为 ext4
从xfsprogs工具版本看，xfs2也悄悄升级到 xfs3 了哦，不知道我这样理解对不。

xfs的龟速删除早有耳闻，现在来看看>=xfsprogs3.0.0的闪电删除！

半分钟删完了，比ext3、ext4、reiserfs都快很多！

以前用过xfs，感觉不如现在的EXT4啊，莫非没有调整对参数？我用的默认设置。

peter_l · 发表于 2009-6-23 09:17:28

一个文件系统再快也快不了多少，倒是换个新型号的大容量硬盘会快不少，有钱再升级下CPU，要是不介意噪声挂上个存储用用，啥文件系统都健步如飞了，哈哈，后面两句不要当真。

SCys · 发表于 2009-6-23 10:47:03

XFS有这样的进步？

如果是改进了小文件处理，倒是可以考虑倒退回XFS

lazyfai · 发表于 2009-6-23 12:15:59

其实单一操作的测试作用不大，应该做些接近实际的，随机的又读又写又删才公平。

解压，耗时10分钟，应该算比较慢吧

压缩，神奇，不到1分钟，难道是xfs尽量用缓存的缘故？

bean@debian ~/temp $ mount -L
mount: option requires an argument -- 'L'
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .
bean@debian ~/temp $ mount -l
/dev/sda6 on / type xfs (rw,noatime,logbufs=8)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)

不是吧。。。xfs3了？

以前最开始也是听别人都说xfs牛，arch装上后就觉得大概linux就如此吧。后来换了jfs，天那我以前过的什么日子。现在换了ext4，确实无论启动，还是小文件操作上比jfs还快

亞利艾爾 · 发表于 2009-6-28 13:29:01

　　我有时候觉得这种很多选择而每个选择都不是最好是个很恶心的事。
　　ext4的性能提升在桌面都很明显。jfs没有用过。xfs老的确实不适合桌面用。

用过两次 xfs ，但都在 3 天内丢失重要系统配置文件而重装系统……
