.BR \-b\ \fIbucket-size
|
||
|
|
Spcifies the bucket size. Allocation is done in terms of buckets, and cache
|
||
|
|
hits are counted per bucket; thus a smaller bucket size will give better cache
|
||
|
|
utilization, but poorer write performance. The bucket size is intended to be
|
||
|
|
equal to the size of your SSD's erase blocks, which seems to be 128k-512k for
|
||
|
|
most SSDs. Must be a power of two; accepts human readable units. Defaults to
|
||
|
|
128k.
