%memused is high

All

I see cpu and memory usage are under control, only cache gets high upto 99% using sar -r command

I did echo3 and cleaned the drop caches

do we need to monitor this , why my application going high upto 99.8% memused in sar command , this is cache memory which is going high

will this cause any performance issues like slowness ?

I understand Kernel should manage this , so do I need to clean up manually ?

Please suggest

prestoctl_svc(8)					      System Manager's Manual						  prestoctl_svc(8)

Name
       prestoctl_svc - Prestoserve control daemon

Syntax
       /usr/etc/prestoctl_svc [ -n ]

Description
       The RPC-based daemon allows remote client systems to monitor and administer a Prestoserve cache and its driver.	The client system does not
       have to be running the Prestoserve software.  The daemon can be started manually, or it can be started each time you reboot by  adding  the
       command to the file of the machine running the Prestoserve software.

       You  must  run the daemon if you want remote client systems to be able to use the command to monitor and manage your system and if you want
       to use the command.  Refer to and to for more information.

Options
       -n     Allows remote client systems to manage a Prestoserve cache and its driver.  The -n option allows remote client systems to change the
	      size of a Prestoserve cache and to change the state of a Prestoserve cache by using remote procedure calls.  The -n option is useful
	      when evaluating or demonstrating Prestoserve capabilities.  Because of security problems, it is recommended that the -n  option  not
	      be used on production machines.

Files
       Generic Prestoserve control device.

       File where you add the
			 command.
