[ https://issues.jboss.org/browse/ISPN-8822?page=com.atlassian.jira.plugin.... ] Radim Vansa commented on ISPN-8822: ----------------------------------- [~gustavonalle] The 2s delay is introduced in {{ChannelFactory.destroy}}: {{eventLoopGroup.shutdownGracefully().sync().getNow();}} uses 2 second delay: {quote} Graceful shutdown ensures that no tasks are submitted for 'the quiet period' (usually a couple seconds) before it shuts itself down. If a task is submitted during the quiet period, it is guaranteed to be accepted and the quiet period will start over. {quote} ... and that method is preferred compared to regular {{shutdown}}. We could try to find out why Netty uses this pattern to closing the event loop. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
