I noticed similar problem when testing read-ahead behavior for fs-on-loop. The basic conclusion is read-ahead in the block device level can complement file level read-ahead, for the latter does not do inter-file read-ahead. But it has to be limited/conservative, because the risk of cache miss is much higher. > into account of prefetching. How about the situation in CLOCK-Pro > project? Sorry, I'm new to CLOCK-Pro, too...
