We've already been over this. You just had the usual "oh my god linux uses free memory as cache" newbie freakout. Lots of memory being cached is completely normal, even expected behavior. If none of your other servers have any memory used as cache,
they are the ones that have something wrong with them. Cache is
good. Cache makes your system
faster. Cache is also still "free" memory that your server will give up and hand over to programs should they ask for it.
Stop freaking out. Stop messing around with your VM modes -- disabling cache hurts your systems -- and undo the changes you did. (If you don't know how, just reboot your system.)

also slow compare other rest servers.
This problem is completely unrelated to memory. It has
6 gigabytes of free memory. You don't have to keep prodding at VM modes. The memory's fine, or was until you started messing with it.
What, exactly, is slow? Forget the memory already and tell us what
performance problems you're having. What's your load average?
