mwget 多线程版本wget下载工具

linux运维在操作linux过程中,用得最多的linux下载工具想必一定是wget,没有看到哪一台服务器没装过wget的,或许有人使用 ftp下载，也有人使用多线程的axel以及ProZilla,毫无疑问这两个工具都非常的出色,但是对于习惯使用wget的人来说显得不适应,于是老外便开发了多线程版本的wget工具mwget,m表示multi多线程的意思.

1. 安装mwget

官方地址：http://sourceforge.net/projects/kmphpfm/?source=dlp

# cd /usr/local/src/
# wget http://jaist.dl.sourceforge.net/project/kmphpfm/mwget/0.1/mwget_0.1.0.orig.tar.bz2
# tar -xjvf mwget_0.1.0.orig.tar.bz2
# cd mwget_0.1.0.orig
# ./configure
# make
# make install

configure过程中如果出现如下错误，请安装大于等于0.35版本的intltool

checking for intltool >= 0.35.0... ./configure: line 6824: intltool-update: command not found
 found
configure: error: Your intltool is too old.  You need intltool 0.35.0 or later.
# yum install intltool

2. wget vs mwget速度测试

以下使用下载2.4.5版本的mongodb来取样.

2.1 mwget速度测试

# mwget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.5.tgz
Begin to download: mongodb-linux-x86_64-2.4.5.tgz
FileSize:  90M
 36% [====>         =====>        ===>          ====>          ] [ 33M] [2.0M/s] [ETA:00:28]

mwget速度截图如下：

2.2 wget速度测试

# wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.5.tgz
