Hi,
using 7-zip from 7.zip.org you have 5 compression levels : store, fast, normal, maximum and ultra. Which one does NSIS use? Is it possible to set the compression level?
Thanks,
Ingo
7z compression level?

It doesn't use 7-zip, nor does it rate compression quality that way.
Read about SetCompresser in the documentation for information on the various compressers.

NSIS 2.0 supports LZMA compression, which is the main 7-zip method.
These 7-zip settings are actually settings for the dictionary size, see SetCompressorDictSize in the NSIS Users Manual.
The default (8 MB) is usually a good setting. Note that a higher dictionary size also increases memory requirements when decompressing.

Does anyone know how good NSIS LZMA compression is compared to 7-zip LZMA?
It would be the same provided that you use the same dictionary size.
