Memory usage on Linux

656294Oct 15 2008 — edited Oct 15 2008

Dear All,

I am using 8 GB RAM & 8GB Swap for my oracle database on Linux machine. I have some problem regarding memory.I've notice that our "FREE Memory" keeps on reducing and "Cached Memory" keeps on increasing. My application getting more time to run.

But when I restart the server "FREE Memory" is more & "Cached Memory" is very less at that time same application run faster. As the "Cached Memory" increases it again take more time run the application.

I know that When I start a process that needs a lot of memory to run, the Linux kernel will reclaim memory that had been storing cached data and give it to the new process.

Is it take some time to clear the cache & allocate the memory to the process ??? so the process required more time to exicute ???

How we can limit the cache memory uses in Linux ??

Regards,
Atul Mandale.
