Re: Regarding performance issues with the Emacs 25.1 Windows-build

[Jostein Kjønigsen]

Thanks Eli.

That's absolutely correct, and a major blunder on my part. My bad. Sorry about that!

I've rebuilt the test-setup for Phil's Emacs 25.1-build using the 64-bit DLLs provided by GNU:

http://ftp.gnu.org/gnu/emacs/windows/emacs-25-x86_64-deps.zip

Using Windows Performance Recorder, the build still runs at the same speed as Emacs 24.5 (7 seconds intense start up period) and seemingly loads all external libraries fine (I've tested gnutls, libxml2 and image-support indirectly through eww).

I guess that means that this build is fine as far as I can see. Sorry about the noise.

If this build gets published on the GNU website, I would consider this issue resolved as far as I am concerned.

Thanks for your efforts, everyone!

Yes. This is with all the dependencies added, systematically and scripted, as outlined in the test-setup

procedure. Both builds are tested using the same test-setup. libxml2-2.dll is found in the bin folder for all

tested configurations.

For whatever reason your latest build seems unable to load these dependencies.

If libxml fails to load, my assumption was that other dependencies like image-support, GnTLS support, etc

would also fail to load. So I did a test: I ran the following in a scratch buffer:

(gnutls-available-p).

On your build I'm getting "nil". For the other GNU builds, I'm getting "t". Again: I'm using the exact same

test-setup across all Emacs versions here.

Your 25.1.2-build clearly has fundamental issues with loading external libraries, although I'm not particularly

qualified to point out what is failing here.

I think the problem is that you downloaded a 64-bit build of Emacs,

but your dependencies are from the ezwinports site, which provides

only 32-bit DLLs, and those cannot be loaded by 64-bit programs.

You should either use the 64-bit dependencies from the GNU FTP site,

or wait for Phillip to upload a new 32-bit build to the GNU FTP site.
