Using Metalink to Speed Up DNF Software Package Installation

openEuler Blog Maintainer2023-09-20metalink

Background

In the current openEuler system, the installation of a DNF software package uses the baseurl mode by default. The following uses the OS software repository of openEuler-23.03 as an example to describe the configuration:

[OS]
name=OS
baseurl=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/RPM-GPG-KEY-openEuler

The baseurl mode directly specifies the site for downloading the software package. The server of the repo.openeuler.org site is located in Hong Kong. The use of baseurl has several drawbacks:

SPOF: A SPOF affects the installation of all software packages.
Limited bandwidth: The egress bandwidth of a site is unable to meet the demand of numerous users simultaneously installing software packages.
Network problem: The speed of accessing the Hong Kong site is slow in China or overseas regions, such as Europe and America.

To solve the preceding problems, you are advised to replace baseurl with metalink.

Metalink Principles

The following uses the OS software repository of openEuler-23.03 as an example to describe how to change baseurl to metalink:

[OS]
name=OS
baseurl=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/
metalink=https://mirrors.openeuler.org/metalink?repo=$releasever/OS&arch=$basearch
metadata_expire=1h
enabled=1
gpgcheck=1
gpgkey=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/RPM-GPG-KEY-openEuler

The DNF client accesses the metalink address. The metalink server calculates the mirrors with fastest host accesses based on parameters such as the host IP address, mirror egress bandwidths, and carriers, and selects top mirrors, sorts them by priority, and returns the mirror list to the DNF client. The DNF client then caches the list file locally. Later, DNF downloads the software packages from the mirror list based on specific algorithms.

Note: openEuler has 27 mirrors across Asia and Europe. For details, visit the following website:https://www.openeuler.org/en/mirror/list/

Comparison between Metalink and Baseurl

To verify the actual effect of metalink, we conducted a simple comparison test between metalink and baseurl in terms of the software package installation speed.

Procedure:

Run openEuler-23.03 in Docker container mode and access the container.
Run the dnf install golang command to install the Golang software package and dependencies (242 MB in total).
Record the time elapsed from entering confirmation information to completion of all package downloads.

Repeat the preceding steps on hosts in different regions for three times in metalink and baseurl modes, respectively. The results are as follows:

Host IP Address	Host Location	Host Bandwidth	Installation Mode	First Time	Second Time	Third Time
123.60.110.6	Shanghai	100 MB	baseurl	12m14s	10m22s	13m11s
123.60.110.6	Shanghai	100 MB	metalink	20s	25s	25s
139.9.250.51	Guiyang	100 MB	baseurl	9m33s	10m29s	10m11s
139.9.250.51	Guiyang	100 MB	metalink	20s	20s	20s
139.159.199.31	Shenzhen	100 MB	baseurl	2m40s	2m26s	2m20s
139.159.199.31	Shenzhen	100 MB	metalink	2m14s	3m12s	2m23s
101.44.36.113	Turkey	100 MB	baseurl	35s	34s	35s
101.44.36.113	Turkey	100 MB	metalink	35s	25s	33s
13.39.48.16	Paris	No limit	baseurl	60m+	60m+	60m+
13.39.48.16	Paris	No limit	metalink	58s	52s	56s
18.197.160.221	Germany	No limit	baseurl	60m+	60m+	60m+
18.197.160.221	Germany	No limit	metalink	45s	48s	49s
44.205.20.228	United States	No limit	baseurl	60m+	60m+	60m+
44.205.20.228	United States	No limit	metalink	24s	18s	22s

Note: 12m14s indicates 12 minutes and 14 seconds. 60m+ indicates that the duration exceeds 60 minutes and is not recorded in detail.

According to the statistics, metalink is not inferior to baseurl in any case, with outstanding performance in both China and European regions, significantly improving download speeds.

openEuler.repo Configuration of Each Version

The following lists the metalink configuration of each openEuler version. You can modify the configuration as required. The file path is /etc/yum.repos.d/openEuler.repo.

Note: openEuler-20.09, openEuler-21.03, openEuler-21.03, and openEuler-20.03-LTS have ceased maintenance.
