Analyzing timer job performance

Good morning, I have a SharePoint farm with 3 servers and since last week I have been noticing an issue. Any job executed on server 2 is veeeery slow (it takes more or less 10m to change the status of the jobs, even restarting sptimerv4 it takes the same time to change the status from paused to running) while any jobs executed on the other servers are showing in real time. What can I do debug the timer job on server 2 to find the cause of this slowness?
