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.
I'd make it look like this:
void main()
{
auto input = File("T201212A.IDX"); //Not a class
TaqIdx tmp;
...
From there, I'd use either of `byChunk` or `rawRead`, I don't
know which is most efficient.
TaqIdx[] buf = (&tmp)[0 .. 1];
while (input.rawRead().length)
{
...
}
or
ubyte[] buf = (cast(ubyte*)&tmp)[0 .. TaqIdx.sizeof];
foreach ( b ; file.byChunks(buf) )
{
...
}
Give it a try and see if it runs faster.
