Earlier quoted context omitted.
I regularly use both Windows and Linux, and I can't say that I've ever noticed a performance problem?
The terminals you use in Linux must either be painfully slow or you must be very insensitive to latency issues because the latency on Windows console is really high. When I type something I expect it to appear immediately ( A lot of basic commands in general run more slowly on Windows but I don't think that's the terminal's fault so much as it's lack of optimisation on the command itself.
Maybe it is just me (willing to accept it is!), but I actually have to try to notice any difference, and even then, it's barely noticeable.
