      I was thinking it might be nice to have Unbound's cache sit in a RAM drive for a system that has a slow spinning hard drive, but an abundance of RAM. Any chance this is possible without much trouble?

        @DWAyotte Judging from the fact that unbound ram usage skyrockets as more lists are loaded, I think it has everything in ram in the first place, without any cache file.
        There is an option that can be compiled in --enable-cache-db, and it can be configured to use redis as a secondary cache server, but this is much more work than a ramdisk.
        And scanning a memory array is probably faster anyways.

          Yep, a whole lot faster as having the same structure on a disk type device : the access would have to flow through the entire file system function calls instead of accessing local processes memory.

          No "help me" PM's please. Use the forum.
