I am developing something that consists of a program I made generating output, and a program I did not make (and would very much like not to have to alter it) consuming it. I am using a named FIFO created with
mkpipe. I suspect I have a performance bottleneck due to the smallness of the Linux FIFO buffer. (And such size cannot be changed without patching the kernel.)
Is there an alternative FIFO-like thing I can use with a buffer of, say, a couple dozen megabytes? The not-made-by-me program can read from anything that can have a filesystem name -
/dev/stdin, a named pipe (like it's doing now), a real file,
Even a third-party free kernel module could do, if no other alternative is available.
