I am going to go off the beaten path here. If you really want
speed
for a file like this one way of getting that is to read the
file
in as a single large binary array of ubytes (or in blocks if
its too big)
and parse the lines yourself. Should be fairly easy with D's
array slicing.
my favourite for streaming a file:
enum chunkSize = 4096;
File(fileName).byChunk(chunkSize).map!"cast(char[])a".joiner()
Is this an efficient way of reading this type of file? What
should one keep in mind when choosing chunkSize?
