[Lessfs-users] Evaluation of deduplication

[Kuniyasu S. <k.s...@ai...>]

Dear,

I'm looking for a method to evaluate deduplication.
Do you know any good methods?

Recently I tried files which repeats 256 bytes random data or 257 bytes random data. 
Variable-length deduplication will deduplicate both files well.
Fixex-length deduplication will deduplicate the file with 256 bytes random data, 
but will not deduplicate the file with 257 bytes random data.
