I am using POST.vi from HTTP Client Palette across my demo without any problem (100ms between request response) except one REST API which creates 5s delay.
When I use modified POST example from HERE with the same REST API, I get response withing 100ms.
I can't gen into the POST.vi as it is password protected.
I have used Wireshark to debug it and set the HTTP request header into the way POST.vi does it int the example snippet with the result of 100ms delay.
Using curl on ubuntu results also in 100ms delay.
I use POST.vi as a buffer: so url specifies IP address of the device with the REST API and the buffer carries data in JSON format.
Don't you know what could create that delay in POST.vi?
Thank you for any idea.
