I'm not sure about the ggsend command, but you'll only get data when that 
process either flushes it's output, or when the buffer becomes full and is 
flushed automatically.  So if there's relatively little output it will come 
all at once, and there is nothing you can do about that without changing the 
ggsend program to flush it's output more often.
