+"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 xz compression performance relative to trinity
* bender and trinity run same lzma version
- * is xz faster or slower than lzma?
-
+ * is xz faster or slower than lzma?
