FYI,

As of the Creators Update, Microsoft's so-called "Windows Subsystem for
Linux"(*) seems to be mature enough now to compile and run the Unix
version of POV-Ray, opening up another way to run a console version of
POV-Ray on Windows machines.

Performance seems to be just as good as the native Windows binaries --
as a matter of fact, on my machine the Unix variant of beta.7 (compiled
with g++ 5.4.0) comes out slightly ahead by about 1%.


Note that to compile POV-Ray on the Linux subsystem, in addition to the
various library packages listed in `unix/README.md` you will also need
to install the following development tool packages:

    autoconf
    gcc
    g++
    make

(plus various packages automatically installed when selecting the above)

In my experiments, I used "sudo apt-get install <PACKAGE>" to install
the packages.


(*I have no idea why Microsoft calls it that way round; from my
understanding "Linux subsystem for Windows" would be a better name.)

Add `pkg-config` to that list, otherwise POV-Ray's `./configure` script
may fail to properly identify the OpenEXR library.

For the records: With beta.8, the Linux subsystem binaries now give me a
performance advantage of just shy of 15% over the native Windows version.

Wow, Cool! Very much looking forward to seeing what I get on my Ubuntu 
system.

 From the company that named their 32-bit subsystem WOW64 :)

I have one thing I've been wanting to write up...
In the kitchen of my animation, the tile floor is superellipsoids with a 
box for grout between the tiles.
When the camera looks at this floor, Windows renders this 10x faster 
than Linux/gcc [1].  (The grout must be present for the extreme 
variation.) At least my theory is it's windows vs. Linux.  The problem 
with my theory is that my Windows box is also my only hyperthreaded i7 
cpu. My linux boxen are all i5(s).  But I don't think it's the CPU, I 
think it's the compiler.  Anyway, now I have to write this up as a 
proper test. I thought it might be interesting to compare against the 
clang results, too.

[1] The difference is so striking, 2.7 minutes vs. 30 minutes, that I 
thought of modifying my renderfarm to support "prefer this named box for 
that range of frames".

We did recently fix a - sometimes significant - 'compiler' related 
degrade with AA mode 2 (+am2) where the windows compiler was OK, but gnu 
g++ and clang were slow. See: https://github.com/POV-Ray/povray/pull/270 
merged April 12, 2017.

Though we saw nothing like a 10x difference.

This would have to be examined in more detail.

Do you still see this speed difference with current beta versions?


With "Windows Subsystem for Linux" now able to compile and run POV-Ray,
it should be easy to figure out whether this is a matter of the CPU or
the compiler: Just run POV-Ray for Windows and POV-Ray for Unix on the
same machine. If the factor 10 speed difference is absent, the compiler
is free of guilt; if it is present, it must be the compiler that makes
the difference, and we might want to figure out how to get better
performance out of g++ for whatever piece of code is affected by this.

Also, it might be interesting to compare the performance on different
CPUs, to see whether the Unix performance loss is a general problem or
limited to a particular class of machines. We're in contact with some
folks at AMD who might be able to test-drive a sample scene across a
wide range of different machines (both AMD and Intel).

I was experimenting with this last year when they released Windows Subsystem for
Linux. See here:
http://news.povray.org/povray.unix/thread/%3Cweb.57ad73e9a051fa67194284cc0%40news.povray.org%3E/

tl;dr - still slower than running on native Linux
