Tomás Fernández Löbbe commented on SOLR-6845:
---------------------------------------------
I see now, the problem is that core reload creates a new core and then opens a
new searcher, so reloading a core calls the firstSearcherListener and then the
newSearcherListener.
> figure out why suggester causes slow startup - even when not used

> 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.
