RFC: zstd as compression algorithm

[dnehring]

Hi,

Veeam is using zlib and lz4 as compression algorithms for a long time. I suggest to add a new compression algorithm to all Veeam products: zstd. It seems to get the standard compression algorithm for many new projects, encryption ratio is much better than lz4 and since zlib supports multithreading encryption and decryption is also very fast.

Perhaps Veeam consider to evaluate this algorithm for a future inclusion in their product lines?

Hi Dirk,

I believe it makes sense to investigate it a bit deeper in order to be sure that it will allow us to achieve better performance without potential side-effects like over-consumption of resources. Anyway, your feedback is much appreciated!

Thanks!

Yes, we will take a look. But I also wanted to add that LZ4 implementation has been dramatically improved in v11. We're seeing slightly better compression ratio and much faster decompression speed.

Great to hear. I think zstd will really be an improvement for the product. Nearly same speed as lz4 (single thread), better speed with multi thread support and better compression ratio.
