How to clear cache from memory in Linux?

Answer:

From time to time, you might observed memory in Linux aren't free'ed after used, and they can be shown in the cached column of the free command.

Mã:

# free -m

# sync; echo 3 > /proc/sys/vm/drop_caches

or

Mã:

# sync ; sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'

And try the free command again.

Mã:

# free -m

có nhất thiết phải flush cached không? vì cached sẽ làm cho vps nhanh hơn?
