After some discussions i would like your option on those two topics: A) enabling higher than default ICA Encryption, is this a limiting factor in terms of scalability? This is handled by CPU, so i guess there will be a higher CPU usage. B) Setting a VDA to "SecureICA RC5 128-bit" even if the Session is opened through ADC Gateway and encapsulated in SSL, what is the benefit then, or other way round: could this combination of having ICA Proxy enabled + using ICA encryption be a reason for bad user experience in terms of getting input lags/delays?
