title: Identity server 4 - GetToken slowness intermittently
body: <p>We have implemented Identity server 4 for our API suite and we have a SLA of 6 secs for the clients that consume our service.</p>
  <p>What we have observed is first request of the day to generate the token for all the clients takes around 6-7 seconds, subsequent request takes 100-200ms.</p>
  <p>We are unable to pinpoint the setting that is contributing to this, as we do not reset AppPool/IIS.</p>
  <p>Any help here would be appreciated.</p>
  <p>PS: We fetch clients from DB and all the token settings are being set here.</p>
