Large vectors in C

[Hinko Kocevar]

I'm using avro C to serialize vectors of 100k elements (double, long,..) for 
example. Currently I'm doing this in a loop that goes over a vector `v` of 
doubles:

                    avro_value_append(&value_value, &element, &new_index);
                    avro_value_set_double(&element, *(v + i));

Performance is poor, terrible in fact. Is there anyway to speed this up? Is 
there any other approach?

Cheers,
Hinko
