How to improve software source installation speed?

Hello everyone, I’m experiencing slow software package installation speeds when using openEuler via the software repository. Are there any methods to improve the installation speed? For example, configuring a domestic mirror source, adjusting the number of download threads, or using caching? I’d appreciate any practical, actionable tips—thank you!

It is recommended to use the Huawei Cloud mirror or Mirrors from Nanjing University, as they offer faster speeds.
