It might be disk access time. Or an anti-virus program interfearing?

With antivirus (windows defender) disabled, compile times go down 
to ~1.7 seconds.

Running under whatever bash emulation layer git comes with. 32 
bit compiler I guess so from dmd --version. Is there a 64 bit 
compiler available for Windows? This is what I get after 
installing the d exe.

I've never had any problems with it but you can disable scanning 
for particular directories instead of disabling the whole thing.

Since even with anti-virus off, comple times are still high, I'm 
not pursuing disabling it as a solution. I'm leaving it alone for 
now, might come back to figure this out in the future.

On my laptop with Core i3, Win 8.1 and DMD 2.067, "dmd hi.d" 
takes 0.64 seconds to produce a 32-bit exe.
No antivirus installed (built-in one disabled).
