title: Change number of threads for Jenkins server
body: <p>I installed Jenkins on my vserver. When I had a look at htop Jenkins was running with 30 thread, each was allowed to allocate 247MB memory and up to 1181MB virtual memory.</p>
  
  <p>Because I've only a small vserver I tried to change the number of threads. But I could not find any configuration file.</p>
  
  <p>I installed jenkins via <em>aptitude install jenkins</em> and in htop I can see that Jenkins is running from: <em>/usr/bin/java -jar /usr/share/jenkins/jenkins.war</em></p>
  
  <p>Tomcat isn't installed as well as jetty isn't installed.</p>
  
  <p>Where is the information about the number of threads saved? Or how can I reduce the number of threads for Jenkins?</p>
