title: How to improve Jenkins server performance?
body: <p>Our Jenkins server(linux machine) slows down over a period of time and it gets unresponsive. All the jobs take unexpectedly long time(even though they run on slaves which are different machines from server). One of things I have observed is increase in the number of open files. The number seems to be increasing as shown in the image below. Does anyone have a solution to keep check on this without restarting the server? Also, are there any configurations/tweaks that could improve the performance of the jenkins server?</p>
