See for the change which apparently came in for 5.14.

As the author notes 8k is an arbitrary figure. (And arbitrary is always stupid.)

On every system I've checked -- including various flavours of Windows, one Linux and 1 BSD -- the optimal buffer size for disk IO is 16k or 64k.

But for pipes and sockets, 4k is already too big for many purposes.

I guess the best solution would be to expose setvbuf().
