I try to sent massive log to test fluentd will handle the request perfectly.
Config is no problem and work well, but it’s weird that after the pressure testing and make sure the server resource is released, fluentd performance become very slow and is unusual.
After that, I modify config from flush_mode immediately to interval, and seems the situation become well as I expected.
I wondering there is anything I misunderstanding about the setting to cause ? Shouldn’t I use the immediately?
