title: Quartz.NET scheduler suddenly taking a while to return a job detail
body: <p>I have been using Quartz.NET in my application a lot over the past few months, and its performance has always been great. Yesterday, it suddenly began taking much longer than usual to execute something like the following:</p>
  
  <pre><code>JobDetail jobDetail = sched.GetJobDetail(jobName, jobGroup);
  </code></pre>
  
  <p>Usually the time it takes is not even noticable, and now it takes at least 2-3 seconds - and when adding up multiple of these the speed is appaling.</p>
  
  <p>What can be causing this? If it's any help, I'm using Quartz.NET with an ADO.NET store, and access to this database seems as fast as ever.</p>
