Tune HA timing,is it possible

Hi, Is it possible to tune time required to reboot VM in case of host failures. in our test we powered off one of the Host. Manager was still showing both Guest and Host as UP for around 5 minutes and after that it took another 4-5 minutes to start VM. Is there any tunable parameter that can be modified to bring down the time required to recognize Host failures. Thanks
