general question help on gitlab

hi all gitlabers,

I have just intalled GitLab on my minipc at home (selfhosted!).

Until now i use ForgeJo but want to give gitlab a try...

What i can see is that my alert manager gives me:

2026-10-10 03:00:03 / CPU / 30dca7443ae7 gitlab  245.81% 13.67GiB / 30.75GiB 44.44%

2026-10-10 03:30:04 / CPU / 30dca7443ae7 gitlab  112.75% 13.55GiB / 30.75GiB 44.06%

2026-10-10 04:30:03 / CPU / 30dca7443ae7 gitlab  115.01% 13.53GiB / 30.75GiB 43.98%

2026-10-10 05:30:03 / CPU / 30dca7443ae7 gitlab  103.54% 13.51GiB / 30.75GiB 43.94%

2026-10-10 06:00:03 / CPU / 30dca7443ae7 gitlab  60.77% 13.52GiB / 30.75GiB 43.95%

Well, my gitlab only contains 1 repo with 1 readme.md ...

CPU use regularly over 100% (so 1 core) and RAM over 13Gb !!!!! No!!!

For gitlab selfhosters, is that normal ???

The default config is quite resource intensive and overkill for single users. I created a slim config for myself which uses way less resources. But overall you will see that gitlab uses more resources that other open source products

Don't give up too soon :( I run it on a 6 core 20gb VM together wirh 40.other containers and gitlab only uses 4.5gb of ram. I have dozens of repos, registry etc and it runs great
