Re: [lwip-users] LWIP UDP throughput with Iperf

The amount of memory used depends on your application. There is no reason to queue UDP datagrams unless you don't get them as they come. API ? NO_SYS ? port ? layer-2 driver ? data size ? stats ? frames per second ? memory usage ? app details ? If you are expecting high-performance, you should be

Hi, I am using bsd socket API. App is : iperf3(ported) NO_SYS: 0 layer-2 driver: proprietary driver (wifi) data size: approx. 2 MB  per second (getting bandwidth ~ 15 Mbits sec). memory usage: max usage around 250 KB (MEM_SIZE), MEMP_MEM_MALLOC is in use.   Driver should not be a prob

Data size can't be 2MB/s, by data size I mean the size of the data chunks you are handling in each frame, you expect to handle an amount of data in a period of time, and that data is handled in pieces, if pieces are too short you need to handle many pieces, if pieces are too long, you need more
