As far as i know, the capacity of each PG should be set smaller for performance reasons
due to the existence of PG locks, thus shall i set the number of PGs per OSD to 1000 or
even 2000? what is the actual reason for not setting the number of PGs per OSD? Is there
any practical limations on the number of PGs?
