Try this;
import std.mmfile;
scope mmFile = new MmFile(T201212A.IDX);
TaqIdx* arr = cast(TaqIdx*)mmFile[0..mmFile.length].ptr;
for (ulong i = 0; i mmFile.length/TaqIdx.sizeof; ++i)
{
// do something...
writeln(arr[i].symbol);
}

Won't help with speed, but you can write it with less repetition:
align(1) struct TaqIdx
{
align(1):
char[10]
Did you try setvbuf method of std.stdio.File?

I have never used readExact so far, so I don't have many
suggestions. But try to not pack the struct.

Given he's using a raw read, I suspect he doesn't

Thank you!

I expect you'd get better performance with std.stdio rather than
std.stream. stream is class based and (AFAIK) not as optimized
for performance.
