It sounds as though when trying to send at a high data rate you get
packet loss, but the sleep(100) slows everything down sufficiently that
whatever is dropping packets can keep up.  Note that with UDP packet
loss is not particularly surprising, or necessarily a bug.  I suggest
you track down where the packets are being dropped - this should make
the reason for the loss more obvious, and so make it possible to suggest
a solution.
