Is that the case? If the system has not enough memory, the kernel buffer will be used for other purpose, and the kernel cache will not work very well anyway. In my understanding, the problem is, even if there's enough memory, the kernel's cache does not work as expected. -- Tatsuo Ishii SRA OSS, Inc.
