You probably meant me. If we create MySQL client without using C

attract some people who write web apps to D. The same applies to
PostgreSQL for which I wrote client without using a C binding.
Why would a reimplementation be much faster? Is the C library "slow"? Or
is there any overhead I'm not thinking of?
There is always a function call overhead and also most of the fields are
returned as strings, whereas in underlying protocol they are encoded
binary, i.e. int is not sent as its decimal string representation but as
4 bytes. This saves some time taken by string to int conversion (parsing).
I see. I've looked a bit at the C library, and it seems the protocol
isn't very stable. Trying to support older MySQL versions and keep up
with protocol changes might be (too) tedious.
