-To check the difference we made experiments using `zwrapbench` with zstd and zlib compression (both at level 3) with 4 KB blocks.
-The input data was git repository downloaded from https://github.com/git/git/archive/master.zip and converted to uncompressed tarball.
+To check the difference we made experiments using `zwrapbench -ri6b6` with zstd and zlib compression (both at level 6).
+The input data was decompressed git repository downloaded from https://github.com/git/git/archive/master.zip that contains 2979 files.
 The table below shows that reusing contexts has a minor influence on zlib but it gives improvement for zstd.
-In our example (the last 2 lines) it gives 15% better compression speed and 6% better decompression speed.
