RAMDisk works allocating on RAM what usually the system will load from HDD, doing this you will gain performance because HDD's are mechanical and have some delay (0~200ms) to spin the physical disk, while RAM is digital and doesn't have any delay. So basically RAMDisk will turn you RAM into an "mini-fast-HDD"

sphere only use HDD to load/save scripts and save files, and after loaded, all data is already allocated on RAM and processed by CPU, with no HDD usage. So I don't tested it yet, but -maybe- RAMDisk will not bring any performance gain on sphere

my live server run on a old intel xeon L5630 where sphere worldsave took ~20s, and here on my PC (core i5 - 4th gen) the same sphere using the same save files took 8s. So if you're looking for performance gain on worldsave, maybe the best option is an faster CPU. Also using an SSD instead HDD -maybe- will help too, since SSD are digital and doesn't have the delay issue of mechanical HDD's
