Anyone knows for sure if intermittent delays will occur when using MATLAB with server license while running Real-Time-Workshop (RTW) on Simulink for real-time, hardware-in-the-loop controls?

I am guessing it's caused by MATLAB when it checks the server (thru network) for licenses for toolboxes, but need to know for sure before dropping the bills for a standalone license.

Delay messes up my engine speed reading (hardware), which relies on counters from a quadrature encoder (hence time delay messes up the timing of the counter)

Previously I was running the same setup on an older computer (32-bit, with standalone license) but after migrating to a faster 64-bit PC with a server license, the delay occurs intermittently.

New computer is using MATLAB R2014B 64-bit, while old one had R2008B 32-bit.

Could also the migration from 32-bit to 64-bit causes the issue? Or is it issue with the compiler? (Tried different compilers, but it didnt fix it)

just saw that small delays (< 0.5 seconds) occurs more frequently than long delays (3-10 seconds)

Any help is appreciated. Thanks!
