Hi,

  1.  We are using Http2 , When compared to 9.0.38 tomcat version , 9.0.62 
version is creating less garbage and taking  more time(2 to 5 seconds) in 
garbage collection during mixed GC phase.
  2.  Are there any recommendation GC setting. Has any one observed these kind 
of problem.
Thanks & Regards,
Venkat.
