any advantage in LVM if we use a fidisk partion to pvcreate other tha using direct disk. some bosy says it is good to avoid using 1st cylender , so creating partion starting from 1st cylender and using this partion for creating a pvcreate to create VG.

Is it good in LVM any perfomance impact

Yes. Partitioning is recommended and may also soon be recommended.

Reason is an increasing number of utilities will complain or report a disk as having no partition table. A nuisance really but RH may actually have a more valid reason why.

I think Oracle and RHEL now recommends paritioning as well.

In our case, we adopted partitioning for EVERYTHING - disks used under LVM and ORACLE ASM are paritioned wholly -- meaning the p1 partition is the only partition on the disk and occupys all of capacity.

The only exception is VxVM managed disks.
