Physical RDM disk format Speed

i use esxi 6.7 update1

and some vm is  configurationed the mscs for physical rdm. for windows 2016

in case of not pRDM , use vmdk with vmware datastore

disk format speed is good

but in case of pRDM , in the MSCS vm

pRDM disk format speed is very slow

same disk is 300GB

one disk(vmdk)format speed is 5~7 second

the other one disk(pRDM) format speed is more than 30second.

i reconfig the vm many times but speed is not good

Is there a way to change the settings to speed up formatting speed?
