(was: We will be glad to have this in 4.10.5 or at least on the 5.0 branch. 
Is there too much effort to backport this issue or is it risky? 
We can contribute if needed because we really need this option to avoid very long startup times.)

> SOLR-6679 was filed to track the investigation into the following problem...
> {panel}
> The stock solrconfig provides a bad experience with a large index... start up Solr and it will spin at 100% CPU for minutes, unresponsive, while it apparently builds a suggester index.
> ...
> This is what I did:
> 1) indexed 10M very small docs (only takes a few minutes).
> 2) shut down Solr
> 3) start up Solr and watch it be unresponsive for over 4 minutes!
> I didn't even use any of the fields specified in the suggester config and I never called the suggest request handler.
> {panel}
> ..but ultimately focused on removing/disabling the suggester from the sample configs.
> Opening this new issue to focus on actually trying to identify the root problem & fix it.
