I mean latency. I send OSC data in every 10ms over eth0 lan cable. With udpsend and udpreceive there is some latency, but netsend (tcp) was all ok.

[PD] [netsend](tcp) is much faster than [udpsend] why??
Hi list, I found this result that [netsend] (tcp) is much faster than [udsend]. It tested on between Mac and Ubuntu connected within eth0. I don't know why udpsend is much slower than netsend. Normally tcp is slower than udp, but netsend with tcp is faster than udpsend. It's strange. Who know it, why it causes?
