+"testfile" is a 175MB avi (southpark_12x12_about_last_night.avi). It's not really compressible, which helps level the ground.

 ==== Notes ====
- * test file is a 175MB avi (southpark_12x12_about_last_night.avi)
  * all targets using 1 core only!
  * The MB/s figure refers to trinity
- * "index" is a performance index relative to trinity
+ * "index" is xz compression performance relative to gzip (probably)
  * bender and trinity run same lzma version
- * is xz faster or slower than lzma?
-
+ * is xz faster or slower than lzma?
