You are not giving much information about your Vim setup (e.g. what 
version, how did you start it, what plugins are enabled, etc...) so here 
are my findings with my standard setup (including various plugins like 
airline):

Running :windo :diffthis on those 2 files gave me:
3.5s on a Win10 i7 Core with 32GB

However, note that Vim needs to shell out and read from a temporary 
file. Also fork() and running external processes is known to be  
considerably slower on Windows than on Linux. And your files are not 
exactly small.

Also note, if those files happen to be living on a network share or the 
tempfiles are on a network share this might slow down I/O considerable 
(as does an on access anti-virus scanner). Also the LargeFile plugin 
might help (in case you have some expensive plugins or autocommands 
running).

Best,
Christian
