Kibana Extremely slow Start Up Time on Openshift/Kubernetes while Optimizing and caching bundles

Yes, I do. And one of them is:

NODE_OPTIONS = --max-old-space-size=1800

That looks pretty small. Maybe I should try to increase this one

All others are some secerts, elastic host url and kibana host

Edit: That did not help

Edit2:

I have added now:

RUN chown -R kibana:kibana /opt/kibana/optimize
RUN chown -R kibana:kibana /usr/share/kibana/optimize

to my Dockerfile.

Now the optimization process sucessfuly done within the build process. Great success.

But now when the container is starting I have again same errors:

Babel could not write cache to file: /usr/share/kibana/optimize/.babel_register_cache.json 
due to a permission issue. Cache is disabled.

and

FATAL Error: EACCES: permission denied, unlink '/usr/share/kibana/optimize/bundles/uptime.style.css'
