Adding more CPU did not solve the issue.
What OS is Solr running on? What tool are you looking at that says 100
percent CPU? For some operating systems and tools, 100 percent might be
very low.
Why have you flipped openSearcher to true on autoCommit? A 60 second
commit maxTime when you are opening a new searcher is fairly aggressive.
What I would probably do here is a 60 second autoCommit with
openSearcher set to false, and autoSoftCommit on a longer interval,
something like five minutes.
How long are your commits taking to warm up completely? To see how long
the last commit took in the admin UI, choose the core from the dropdown,
then navigate through these options: Plugins/Stats, CORE, searcher.
Then look for something in the list that includes warmupTime. It will
probably say "SEARCHER.searcher.warmupTime" and be near the end of the
list. That number should be in milliseconds.
