Honored ContributorI run NicheStack with MicroC OS-II on a 100MHz Nios-II/f with cache on a Cyclone III FPGA and I get this figures:
- UDP (ping) : less than 1ms between request and reply, measured on the wire - TCP : less than 5ms between request and reply, mainly due to application; actually the delay due to TCP Stack and OS is limited to about 2ms As Daixiwen pointed out, you get major improvements with -O2 build optimization, fast Nios core with cache and higher cpu frequency. Anyway, even with a basic system like yours (50Mhz Nios, posibly no cache, debug build configuration without optimization) IIRC you should achieve a UDP round trip time far below 50ms. With UDP do you mean a simple "ping" command or are you implementing a UDP server in your application?
