You are using a new SecureRandom per connection, instead of using a single static pre-initialized SecureRandom. Everytime you create a new SecureRandom(), you need to gather entropy for seeding (a slow process).

SecureRandom does not self-seed until it is first used, which is why the delay does not occur until the call to getSession()
