Hi, 
I have Jenkins master (v2.190.1) installed as EC2 t2.small - it worked as 
expected until i've updated plugins recently and restarted jenkins. 
Now i can see that jenkins process consumes 100% CPU and it's caused  by 
IOwait - disk performance is a bottleneck. 
Jenkins started to do some heavy disk reading which caused running out for 
EBS burst balance - now with 150G EBS i should have around 450 IOPS and it 
seems not to be enough for Jenkins - but it worked just fine a week ago. 
When i track jenkins process with strace i see that it reads/scans every 
job and branch and build i have which probably is the source of the issue. 
How can i check which plugin caused or maybe is it desired behavior that 
after restart Jenkins scan all the files over and over again?
