Hi,

I was wondering about that. Do you mean allocating a new buffer call sp_writer_send_buf()
and then free the buffer. Call alloc and do it again?

Freeing the buffer makes it available for reallocation. I might just get the same physical
memory on my next alloc call. Why not just re-use and save the overhead of free/alloc?

Sorry if I am dense, but it is still very cold...

Cheers,
Remco
