It is expected that reloading segment (especially for upsert) can take one CPU core for some time because it is CPU bound operation. When parallel refresh threads is set to 1, we allow one reload at the same time, so there is no difference reloading multiple segments or one by one, and it will use up to 1 CPU core. I don't know how could CPU usage go up 30-40%. In the second graph, less than 5% CPU usage is expected -- This is an automated message from the Apache Git Service.
