Hello which combination of tricks do I need to maximize the speed for my SC program.
1.) Is there a speed difference between using 40 bit versus 128 bit encryption with MSRC4?
2.) Is there a speed difference between using MSRC4 and SecureVNCPlugin.dsm? (SecureVNCPLUGIN uses old build, probably not....)
3.) Other than resoloution, what other options should I select once connected?
