Fork problem?

Hi,

From Unix command line, I did this

mkfifo fifo
readProgram fifo &
writeProgram fifo

fifo acts as a named pipe between the read and write program.

in Ruby, I did the following

fork { exec readProgram fifo}
system writeProgram fifo

This worked but the performance is much slower than the Unix commandline.

Any idea?

Thanks

So how is:

fork { exec readProgram fifo}
exec writeProgram fifo

in comparison?

Any idea?
