I don't understand why this sometimes takes two minutes between the start commit & /update and sometimes takes 20 minutes? One of our caches has about~40,000 items, but I can't imagine it taking 20 minutes to autowarm a searcher.
What do your cache configs look like?
How big is the autowarm count?
If you have:
<queryResultCache
class="solr.LRUCache"
size="512"
initialSize="512"
autowarmCount="32"/>
that will run 32 queries when solr starts. Are you running 40K
queries when it starts?
