Gitlab-CE Instance has poor performance

Hello,

We are using gitlab-ce 13.1.4 instance in our on premises infrastructure inside docker container. We have assigned it 8GB Memory & 6 CPU Cores.

We have integrated that gitlab with CI tools ( Jenkins & gitlab-ci ).

Problem: While Fetching code from gitlab repositories and pushing / pulling docker artifacts to / from gitlab instance we are facing very worst performance issues.

Also many times it’s throwing error like below.

fatal: The remote end hung up unexpectedly fatal: early EOF fatal: index-pack failed

Can Someone Please Assist here how can we get rid of this issue ?

Let me know If you need more information about this.

Regards, Kushal Mehta
