FBDK/UDP timings [message #1865403]

Hi!

I am running some communication tests with FBDK and UDP so I get better understanding about its advantages and limitations. In order to doing so, I created a simple application (attached) so i can send data between a pc and a raspberry pi 4 over a local cabled network. (Ethernet segment)

So far I got around 50ms between sending and receiving the same data.

Is this the expected timing? Are there any configurations I may change in FORTE in order to achieve better times?

Any suggestions would be very appreciated.

Thanks in advance!

I made new tests on another network.

Times as low as 1ms (monitoring attached).

Certainly a network issue. Not 4diac.

Thanks in advance.

Sorry for the late reply. There can be many influencing factors that effect the network transmition. Not all of them we can influence from 4diac FORTE side. However if you need faster trough put through the stack and os you could look into raw sockets and assembling your packet directly in memory. I never did that but AFAIK this should bring you some advantages. Especially as for sending our UDP packets several parts of the message are not changing.
