It is much faster in encoding because all goes directly through stdin. And even on decoding it is slightly faster, also it requires less memory.

Normally, if you use srep it will copy all the files to a temp folder first which can take a lot of time, plus it requires additional disk space, and also doing its "second pass". With xtool dd, all these steps are obsolete. The output data which comes from srep is compressed immediately if you use compressors which works in stdin/stdout or cls mode (which lolz does not do atm in dsg). For example lzma, lzma2, fast-lzma2 and zstd.

However, a Idea comes to my mind and I will ask César if he can add something to dsg.
