The 7zip archiver gives you the following options:

Compression Level

Allows you to specify the amount of compression while creating archives on an odd scale of 0 to 9. 9 is maximum compression, 1 is minimum and 0 (zero) is no compression (just storage).

While Adding

Use solid blocks: Utilizes 7zip's solid block algorithm, this results in higher compression but makes the archive sort of like a magnetic tape meaning, to extract one file in the block you will have to extract all files upto the file. In general, its best not to use this option unless you want that slight bit of extra compression Use multi-threading (for multi-CPU PCs): Asks 7zip to make use of multi-threading across all your CPUs, useful if your system has more than one CPU

While Extracting

Always overwrite (Default): Always overwrite any existing files Never overwrite existing files: Any files that already exist are not overwritten while extracting Rename existing files: Rather than overwriting, it renames the existing file Rename extracted files: Rather than overwriting, the newly extracted file from the archive is created with a different name

For information on saving these settings to the archive or as defaults read the <archiver> menu in this page.
