-data_cache_size number_of_tiles blocks_per_tile
|
|
|
|
|
Set the size and granularity of the data cache which is used when
|
|
|
|
|
ISO images are loaded and when file content is read from ISO
|
|
|
|
|
images. The cache consists of several tiles, which each consists
|
|
|
|
|
of several blocks. A larger cache reduces the need for tiles being
|
|
|
|
|
read multiple times. Larger tiles might additionally improve the
|
|
|
|
|
data throughput from the drive, but can be wasteful if the data
|
|
|
|
|
are scattered over the medium.
|
|
|
|
|
Larger cache sizes help best with image loading from MMC drives.
|
|
|
|
|
They are an inferior alternative to -osirrox option "sort_lba_on".
|
|
|
|
|
blocks_per_tile must be a power of 2. E.g. 16, 32, or 64. The
|
|
|
|
|
overall cache size must not exceed 1 GiB. The default values can
|
|
|
|
|
be restored by parameter "default" instead of one or both of the
|
|
|
|
|
numbers. Currently the default is 32 tiles of 32 blocks = 2 MiB.
