As one would expect, once block size gets large, it makes no difference whether block-level compression is used.
正如预期的那样,一旦块大小变大,是否使用块级别压缩并没有区别。
In general, you must have blocks of 100k or larger before the block-level compression pulls nearly even with the file-level compression.
通常,要使块级别压缩的效果与文件级别压缩几乎相同,块的大小必须要有100k或更大。
At small block sizes, compression is much worse than file-level compression.
块大小比较小时,压缩比文件级别压缩差很多。
A surprising result is the behavior of block-level bzip2 compression.
令人惊奇的结果是块级别bzip2压缩的行为。
Around 10k block size, block-level compression starts to look moderately good; and at 100k block size it becomes very close to the file-level compression techniques.
块大小约为10k时,块级别压缩开始显得比较不错;块大小为100k时,块级别压缩就非常接近文件级别压缩技术了。
Around 10k block size, block-level compression starts to look moderately good; and at 100k block size it becomes very close to the file-level compression techniques.
块大小约为10k时,块级别压缩开始显得比较不错;块大小为100k时,块级别压缩就非常接近文件级别压缩技术了。
