Hello All ,

One of our spring boot micro service connecting to elastic has high response time , while the took time itself is 50ms the service response time is high . After taking couple of threaddumps I see there are in total 10 threads in each dump and 1 or 2 out of 10 threads are in RUNNABLE status always and remaining threads are either in WATING or TIMED\_WATING. The below thread says waitedTime after thread contention monitoring was enable and it shows waitedTime": 4985607ms .

1. What should be my starting point for analysis?
2. What could cause these threads to wait for so long ?

Appreciate your help on this .

I did profiling of my client code which is calling elastic . Most of time is spent on Class CountDownLatch
