Well for one thing, opening a VI console of a VM and opening a RDP of a VM are quite different and use entirely different protocols. If you suspect opening rdp is slower, you might want to check:

i) opening a rdp is allowed by firewall

ii) Opening a rdp of a different VM inside a the VIconsole of another VM is also slower? then we can confirm that rdp session is being crunched by some process.
