Gitea mirroring gitlab repository takes too long

[darrel1234]

Mirroring a Gitlab repository from Gitea takes a long time. Gitea runs on Kubernetes using this helm chart - https://github.com/jfelten/gitea-helm-chart, AWS EFS as the PV and AWS RDS as external DB. The code is around 1MB and has 535 tags

I've tried:

1. Increasing the Instance type for RDS
2. Increasing the Pod Spec CPU & Memory

... but it still takes around the same time (1 hour)

Here are the specifications for the Pod & RDS:

POD resources:
gitea:
requests:
memory: 1Gi
cpu: 1000m
limits:
memory: 1Gi
cpu: 1000m
memcached:
requests:
memory: 1Gi
cpu: 1Gi

RDS Instance Type - db.m4x.large (4vCPU, 16Gib)
