The underlying problem most likely is that csvReader has (AFAIK) 
never been properly optimized/profiled (very old piece of the 
library). You could try to implement a rough csvReader using 
buffer.byLine() and for each line use split("|") to split at "|". 
That should be faster, because it doesn't do any checking.

Non tested code:
string[][] res = buffer.byLine().map!((a) => 
a.split("|").array).array;
