Hi Mulyadi,
You are quite right. There are many things which can affect the tests. I
think the most import two factors are (1) how files are accessed, e.g.
sequentially or randomly, (2) which buffer cache and readahead algorithms
are used.
I've read Fengguang Wu's work some where. Basically reada

It will be a quite long answer if you need details. In essence

Hi,
I have been doing a testing to see how Linux buffer cache and readahead
algorithms perform for reading a file from a disk. My assumption is that:
(1) when the file size is less than the available physical memory, buffer
cache and readahead can give better performance even though extra sectors

No, if you simply want to develop external modules, the best/simplest
way is to install your distro kernel development package.
For example, unde
