49 The sequential threshold indicates the number of contiguous I/Os
50 required before a stream is treated as sequential.  Once a stream is
51 considered sequential it will bypass the cache.  The random threshold
55 The sequential and random thresholds default to 512 and 4 respectively.
57 Large, sequential I/Os are probably better left on the origin device
58 since spindles tend to have good sequential I/O bandwidth.  The
60 of these sequential modes.  But there are use-cases for wanting to
61 promote sequential blocks to the cache (e.g. fast application startup).
62 If sequential threshold is set to 0 the sequential I/O detection is
63 disabled and sequential I/O will no longer implicitly bypass the cache.
158 	sequential threshold set to 1024 and the random_threshold set to 8.
