...ng custom read functions (in C). By timing various approaches I figured out that one of the bottlenecks in reading character fields is the mkChar() function which on each call incurs a lot of garbage-collection-related overhead. I wonder if there is a "vectorized" version of mkChar, say mkChar2(char **, int length) that converts an array of C strings to a string vector, which somehow amortizes the gc overhead over the entire array? If no such function exists, I'd appreciate any hint as to how to write it. Thanks, Vadim [[alternative HTML version deleted]]
