You just waste memory and CPU time.
[nexthop]  If we want to get a high performace, can we cache using RAMdisk ?
According to your comments, it seems that cache in ramdisk have a lower

I do a google search with ramdisk cache, it seems that Cache in RamDisk will
get a high performance.

I am confusing it.
Could you please give us more information about it ?

thanks
