As the kernel buffers/caches data blocks from the disk, (( maybe ))
it spends more time finding spare blocks than it takes to load the data.
On one machine (128 MB) CPU usage is 95% on another (64 MB) it's 65%
When the file is re-read from cache, (no new pages), it is fast.

Sorry if this is the 3000'th notification you have seen
