I've the same problem yesterday. In stack trace, jenkins is stuck at
hudson.ExtensionList.ensureLoaded(ExtensionList.java:247)

I've found an issue about a similar problem and I've applied the
proposed work-around with sucess

https://issues.jenkins-ci.org/browse/JENKINS-19244

Best regards,

I found this issue is caused by jenkins sshd startup, and then disable it , it's ok now. but still no sure why it is slow.

PS: disable jenkins:
cat $JENKINS_HOME/org.jenkinsci.main.modules.sshd.SSHD.xml
<?xml version='1.0' encoding='UTF-8'?>
<org.jenkinsci.main.modules.sshd.SSHD>
  <port>-1</port>
</org.jenkinsci.main.modules.sshd.SSHD>
