-a Get/set sector count for filesystem read-ahead. This is used to improve performance in sequential reads of large
files, by prefetching additional blocks in anticipation of them being needed by the running task. In the current ker-
nel version (2.0.10) this has a default setting of 8 sectors (4KB). This value seems good for most purposes, but in a
system where most file accesses are random seeks, a smaller setting might provide better performance. Also, many IDE
drives also have a separate built-in read-ahead function, which alleviates the need for a filesystem read-ahead in many
situations.
Gledajuci ovo, i ja sam turio 8, da vidim oce li biti ista bolje.
