Ich habe früher viel RealThinClient genutzt, auch mittlerweile OpenSource. Ist sehr stabil, schnell und einfach zu implementieren
Good choice and great advice, as RTC is the best of them all !
I either do low level using
API for extra tweaking or RTC for anything else, also notice with RTC, you don't need to use its components and classes from the palate, but can use the RAW ones for
TCP and UDP, they are powerful and comes with threading (pool and sync... etc) out-of-the-box that can be switched from Multithreaded (asynchronous) to Single-thread (synchronous) by flipping a bool.
