Disabling TCP delay (Nagle algorithm, tcp_no_delay) globaly on RT Linux

I am sending small messages ( a few strings) frequently ( <100ms) to RESTfull API. I found and tested that http://digital.ni.com/public.nsf/allkb/7EFCA5D83B59DFDC86256D60007F5839 and see much difference using the provided example. The problem I have got is that I am using RESTfull API which is build on top of HTTP and I don't have access to raw TCP port.

 

Does anybody knows how to turn off Nagle algorithm on  RT Linux (cRIO 9035) globaly?

 

I have also tried tcp_no_latency  flag: http://www.linuxvox.com/2009/11/what-is-the-linux-kernel-parameter-tcp_low_latency/ but it is being overwritten on the system startup. Has anybody had similar problem?
