Yes, I/O can also be an issue.

This can be partially mitigated by using rrdcached.

You can also disable modules that you don't really need, like FDB collection.

Thanks,

Hi Wilbert,
have a look at your I/O usage. Maybe your storage is too slow. I had
similar problems and migrate from a VM to a physical server with SSDs.
