Your fast mirror that addresses epel.dionipe.id is very slow.
Either their servers are slow or limit download speeds.
When I installed the Regional Cyber Panel in Indonesia. I get an average speed of 40 kb/s. With this speed it makes no sense.
Proof of a screenshot:
I tried running 2 servers at the same time with the same specifications and server. Server A installs the cyber panel (Very Slow) and Server B tests downloading the video file (154 mb/s).
Please replace it for the Fastmirror. I was very disturbed and wasted my time.
