Its way to clever for the job. If you want to do this seriously get some
NCR ultra scsi cards and rewrite the script files so they do nothing but loop
polling a ring buffer of commands to send and filling in empty slots in an
RX ring buffer.
Now get the U-NET package of fast user space networking. Get the driver
working with it and you have got host->host 40Mbyte/second networking with
NO system call or interrupt overheads
