Hi,

Thanks for replying Here is one observation worth mentioning. On boot system it shows Mapped < Cached (In fact much less)

quite predictable.... during booting phase, your system read() much by doesn't mmap() that much....

After using system for some time following commands are executed. # sync and echo 3 > /proc/sys/vm/drop_cache

Whenever above command is executed I can see Mapped > Cached.

by echoing "3" to drop_cache, you flush the content of page cache as much as possible ... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com
