Re: Pipe problems

Nope.  By definition, pipes have _no_ storage capacity.  They
function as a rendevous-type syncronization point for data transfer
between two processes.  Pipes are for conveniently building
functionality chains, linking several small simple programs together
to make a throw-away complex program.

If you are really asking about improving the performance of data
transfer between to processes, then pipes are the wrong choice
because pipes are implemented as filesystem objects and bring
along all that overhead.

Looking for performance? Then check out using shared memory, perhaps
by using either a shared mmap(2) region or, blech, System V IPC
shmget() and friends.
