> Increasing w32-pipe-buffer-size has no effect on the speed of reading from the pipe. I tried several buffer size values, in combination with several read delay values, but only the read delay has an effect. For example, at 50 milliseconds read delay, it takes ~13 seconds to read 1 Mb of data, regardless if the buffer size is set to 0, 4096, 8192 or 16384.
OK, thanks for clearing this out. It sounds like thee default value
of w32-pipe-buffer-size is doing fine, and w32-pipe-read-delay should
be reset to zero, which will probably happen in a future version of
Emacs anyway.
