+version 3.0+ is 20 times slower than version 2.12
+I wrote a small 64-bit operating system (SIGMAOS) in which I use the lzma decoder. unpacking the file takes 20 times slower than in version 2.12.
+You can download it from https://drive.google.com/drive/folders/0B_wEiYjzVkC0ZGtkbENENzF1Nms
+
+Your linked drive doesn't seem to have any readme or documentation for how this is invoked. Please see:
+
+  https://www.qemu.org/contribute/report-a-bug/
+
+Specifically the host/guest details and the full command line that you have used to run this binary. 
+
+As developers may be wary about running on unknown binary on their systems you may find it quicker to do some experiments yourself. If you run qemu under perf for 2.12 and 3.0+ (or current git) that might give some indication about what has changed.

+[Expired for QEMU because there has been no activity for 60 days.]
