2 GB is really not that much memory for Jenkins that does any real amount of work. At work I have seen Jenkins sometimes use almost 6 GB of memory!
You could connect jconsole to the jvm and check the status of the various memory pools. Also check what the jvm is doing? Is it busy cpuwise? How many threads? Also check how the operating system is doing? Is the host swapping? Is it spending a lot of time in IO wait? Are you using OpenJDK 1.6? We used it for a while but it made our Jenkins very slow. -- Sami Knuplesch, Jürgen kirjoitti 18.7.2012 kello 9.47: > Hello, > > I recently updated to Jenkind 1.470. > > We installed the new CVS-Client. > Sadly the update command is not working because of a bug in Jenkins, so we > disabled this. > > CVS became slow too, so I disabled rlog in my jobs.
