It depends on how the commit is called. You have openSearcher=true, which means the call won’t return until all your autowarming is done. This _looks_ like it might be a commit called from a client, which you should not do.
It’s also suspicious that these are soft commits 1 second apart. The other possibility is that you have your autoSoftCommit interval set to 1000 ms. This is usually far too fast.
