-=== Notes ===
- * test file is a 175MB avi (southpark_12x12_about_last_night.avi)
- * MB/s refers to trinity
- * index is a performance index relative to trinity
- * all targets using 1 core only
- * bender and trinity run same lzma version
- * is xz slower than lzma?
+== A crude CPU benchmark using lossless compression algorithms ==
+=== How to test ===
+
+{{{
+time lzop >/dev/null <testfile
+time gzip >/dev/null <testfile
+time bzip2 >/dev/null <testfile
+time xz >/dev/null <testfile
+}}}
+
+"testfile" is a 175MB avi (southpark_12x12_about_last_night.avi). It's not really compressible, which helps level the ground.
