Delay/ Wait-time in getting access to fork-join thread pool from main applications thread

I have a fork-join thread pool with parallelism of #of cpu's *12 (4 * 12) in my case. They do db operation in parallel. I have enabled time duration logs for all the methods. I see a delay of 20 seconds in accessing fork-join thread pool by the main application thread. I have tried varying the parallelism level but din't see any change in delay/wait-time. Could anyone help me resolve this issue? Thanks in advance.
