That rt thread, also send UDP Ethernet packets. This project was ported from VXWORKS project, but we notice the following difference: Although the rt thread gets its 1 millisecond periodic in high accuracy, the udp is being send in chunks, as if several messages are aggregated before being delivered. Is there any reason for such behavior ?

Is it possible your Ethernet driver has coalesce options enabled?
